Past experimental research has demonstrated that employees who use treadmill desks in a laboratory or an office environment experience physical and mental health benefits (e.g., Sliter & Yuan, 2015). Treadmill desk users are more active, walking about 2 additional miles per day when compared to not using a treadmill desk (Giumetti et al., 2021). While the benefits of treadmill desk use are clear, research exploring how workers use treadmill desks is needed to encourage their implementation and continued use (Tudor-Locke et al., 2014). To the authors’ knowledge, no studies have explored treadmill desk use by employees working from home. However, the home office environment is particularly important to understand due to the recent increase in working from home caused by the COVID-19 pandemic, with 59% of employed adults whose job responsibilities can be done from home choosing to continue working from home all or most of the time (Pew Research Center, 2022). Therefore, the goal of this study was to contribute novel research findings to the literature on active workstations by exploring how treadmill desks are used at home, the perceived benefits of treadmill desk use at home, and what factors serve as motivators or barriers for treadmill desk use at home.

Benefits of Treadmill Desk Use

Sitting for prolonged periods of time at work is associated with negative physical and mental health outcomes including increased neck and back pain, weight gain, negative affect, fatigue, risk of diabetes, cardiovascular disease, and even increased risk of death (Flint et al., 2017; Wilmot et al., 2012). Active workstations such as sit-to-stand desks, cycling desks, and treadmill desks can be used to improve health outcomes for employees who work in seated desk jobs by reducing sedentary behavior and increasing engagement in light physical activity. In a recent randomized-controlled trial examining the long-term effects of active workstations, employees using a treadmill desk engaged in fewer daily sedentary bouts at the workplace when compared to a sit-to-stand desk group and a control group at 12 months (Arguello et al., 2021). Furthermore, reviews of the active workstation literature have revealed that treadmill desks increase energy expenditure more than other types of active workstations (Tudor-Locke et al., 2014) and are associated with greater physiological benefits than a standing desk (MacEwen et al., 2015). In a sample of physicians, treadmill desk walking led to weight loss and reduced body fat when compared to not using a treadmill desk (Thompson et al., 2014). Furthermore, treadmill desk use is associated with better recall and attention (Labonté-LeMoyne et al., 2015), more vigor and positive affect (Giumetti et al., 2021), and greater arousal, less stress, and more task satisfaction than standing (Sliter & Yuan, 2015).

Fortunately, treadmill desks provide these benefits while not sacrificing most task performance (Cao et al., 2016). Treadmill desk users may experience modest, short-term decreases in motor performance (Straker et al., 2009), but cognitive performance and long-term work performance are not affected (Ehmann et al., 2017; Koepp et al., 2013; Sliter & Yuan, 2015). However, it is unknown how the benefits of treadmill desk use in the workplace compare to the benefits of treadmill desk use at home. Furthermore, although there is no research on the organizational benefits of treadmill desks specifically, past research has demonstrated that workplace physical activity interventions more broadly are associated with less absenteeism (Grimani et al., 2019). Additionally, companies that provide strong health promotion programs for employees have better performance outcomes (Goetzel et al., 2019). Therefore, organizations may choose to invest in employee health and well-being via active workstations like treadmill desks, and an understanding of the motivators and barriers to their use are important for their successful implementation.

Motivators and Barriers to Treadmill Desk Use

All the research examining treadmill desk use has occurred in either a research laboratory or an office setting, with only one study exploring the motivators and barriers to treadmill desk use in an office setting. Cifuentes et al. (2015) conducted a qualitative study with five female university employees who used a treadmill desk in their offices for 6 months. Usability, safety, comfort, and productivity were identified as factors influencing treadmill desk use. Employees found an electric treadmill desk easy to use, used it more often when they had control over their daily schedule, and reported feelings of enjoyment, increased energy, higher concentration, and positive mood after 4 months of use. However, they also identified several barriers to using the treadmill desk, such as it being difficult to move everything from the sitting area to the standing area, knee and foot pain during the first few weeks of use, the noise negatively impacting communication, interruptions throughout the day, and derogatory comments from coworkers. These findings could be used to improve usability and acceptability of treadmill desks in an office environment with the goal of improving worker health through reduced sedentary time. However, it is unknown if the motivators and barriers to treadmill desk use are different when working from home.

Present Study

To address these gaps in the literature, our study aimed to answer the following research questions (RQs):

  • RQ1: How are treadmill desks used when working from home and by whom?

  • RQ2: What are the perceived benefits of treadmill desk use at home?

  • RQ3: What motivates individuals to use their treadmill desks when working from home?

  • RQ4: What barriers exist to treadmill desk use when working from home?

Method

Participants

Twenty participants completed the study between February 2022 and April 2022. The study was constrained to 20 participants due to funding limitations. Participants were eligible if they had a treadmill desk at home, worked from home at least one day per week, lived in the United States, and were at least 18 years old. Participants were recruited via study advertisements emailed to treadmill desk owners via Lifespan Fitness and iMovr and posted in relevant groups on LinkedIn, Twitter, Facebook, and Reddit. Participants were compensated for their time with a $50 Amazon.com gift card.

Measures

Structured Questionnaire

Participants completed a 23-item structured questionnaire to report their demographics, characteristics of their home environment (e.g., neighborhood type), employment (e.g., type of job; hours per week; work location), and treadmill desk characteristics (e.g., manufacturer and date of purchase). Participants uploaded an optional photo of their home treadmill desk and provided explicit permission for the photo to be used in presentations and publications of this research.

Interview Script

Nineteen interview questions with optional follow-up questions were developed to explore how participants used their treadmill desk while working from home (e.g., hours per day; speed of walking) and the perceived benefits, motivators, and barriers to treadmill desk use. The interview questions included items such as “What motivates you to use the treadmill desk?” and “What makes it difficult for you or prevents you from using the treadmill desk?” The complete set of interview questions is provided in the Appendix.

Procedure

The study was approved by the Eastern Connecticut State University Committee for the Use of Human Subjects in Research (CUHSR). Interested participants who responded to the study advertisement were emailed a survey to complete in Qualtrics. The survey began with participants providing informed consent, followed by pre-screening questions to ensure participants met the study requirements. After passing the prescreening questions, participants completed the structured questionnaire. The researcher confirmed they were in the United States using the Qualtrics provided location. All eligible participants were sent an invitation to schedule a 30-min interview with a member of the research team.

Interviews were conducted virtually using Microsoft Teams. Video and audio were recorded with permission, and the automatic transcription feature was used. The researcher also took notes on the participant’s answers to help with future transcription editing. The researcher followed the interview script, using pre-planned prompts when additional information was needed to further understand a participant’s response.

Quantitative data were analyzed using IBM SPSS v25, and qualitative data were analyzed using Taguette, a free and open-source tool for qualitative research. Qualitative data were analyzed using a type of thematic analysis known as Template Analysis with 6 phases (Brooks et al., 2015). The Template Analysis approach was selected as a good fit for answering the research questions because it allows for a priori themes, and it also lends itself well to a team-based analysis (Brooks et al., 2015). This manuscript’s first author is a home treadmill desk user. To minimize possible bias, the second through fourth authors, who have never used a treadmill desk, conducted all interviews, transcription editing, and initial coding and theme generation. The first author provided methodological guidance on how to conduct the analysis and collaborated on the development of the coding template.

In phase 1 of Template Analysis, familiarization, the researchers independently reviewed the recorded interviews and edited the transcripts for accuracy. In phase 2, preliminary coding, the researchers independently coded the transcripts, using a combination of a priori themes based on the interview questions (e.g., motivators, barriers to use, perceived benefits) and subthemes that they generated during this stage (e.g., COVID-19 pandemic). In phase 3, the researchers collaboratively organized the subthemes into meaningful clusters. For example, the team organized the subthemes of mental perceived benefits, physical perceived benefits, and work-related perceived benefits within the broader theme of perceived benefits at this stage. In phase 4, defining the initial coding template, a full template of themes and subthemes was generated. In phase 5, this coding template was applied as data analysis continued, and the template was collaboratively modified as necessary. For example, a theme called interpersonal was later split into a subtheme of perceived benefits called social perceived benefits and a subtheme of barriers to use called social concerns to better represent the relationships within the data. When new subthemes were generated, the researchers returned to the transcripts to add the subthemes where appropriate. In phase 6, the researchers finalized the template of themes and subthemes and applied it to the full data set.

Results

Treadmill Desk Use

Table 1 summarizes participant demographics, Table 2 summarizes features of their employment and treadmill desk usage, and Fig. 1 shows example photos of participants’ home treadmill desk set ups. Participants described using their treadmill desk anywhere from once per month to seven days per week, from 45 min to 10 h per day (with breaks), and at a comfortable walking speed of 0.7–3 mph. Sixty-five percent of participants obtained their treadmill desk in 2020 or 2021. There was a non-significant negative correlation between length of time owning a treadmill desk in months and hours used per week, r(19) = -0.21, p = 0.39. Participants used their treadmill desk during meetings, video conferences, phone calls, webinars, and when reading, writing, studying, entering data, using online chat, using spreadsheets, emailing, teaching, grading, watching videos, and searching the Internet. They also used their treadmill desk for non-work activities, like watching TV shows, videos, or sports, online shopping, personal emails, listening to audiobooks or podcasts, and working on personal finances. They described walking on the treadmill as an effective way to multitask and create time for physical activity, like a “two for one” and “a total win” (Participant 8), especially if they experienced time constraints:

And I also am relatively busy. You know, I have a full-time job. I have 4 kids. It's, uh, like my opportunities to go for a long walk, like they don't exist. I don't have the time for that. Even though I enjoy walking and I know it will keep my body healthier… And so if I don't use my treadmill desk, there's no way I am even going to get 10,000 steps in a day. (Participant 20)

One participant described the advantages of using a treadmill desk at home versus the office:

When you work from home, it's a lot easier to kind of have a treadmill desk. Uh, if you're in an office, it might be a little bit different, but you know, I can put a pair of shorts on and some workout gear and you know, I'm not feeling… (Researcher: Yeah, they won't even notice.) Exactly. (Participant 11)

Participants either described treadmill walking as the only planned exercise they got during the day or described a variety of physical activities they engaged in beyond treadmill walking, such as rowing, biking, walking outside, swimming, surfing, skiing, skim-boarding, hiking, running, weightlifting, using an elliptical, yoga, golf, pickleball, snowshoeing, working out at a gym, group exercise classes, spin classes, kickboxing, martial arts, and working out with a trainer.

Perceived Benefits of Treadmill Desk Use

Participants experienced a variety of physical, mental, work-related, and social perceived benefits from using their treadmill desks (see Table 3). Physically, 11 participants described being less sedentary and more active, and nine gained cardiovascular or fitness benefits:

I can't be away from my computer and so definitely having the treadmill has allowed me to get movement in during a time of day when before I would have just been sitting, which would have been contributing to, you know, less than ideal health outcomes. And so now I kind of feel like, wow, I can do my job and I can get some exercise at the same time, which I never, you know, prior to that really thought was an option because my work is all computer based. (Participant 19)

Table 3 Theme: 1.0 Perceived Benefits

Mentally, nine participants experienced better focus and felt more alert and less tired, with seven participants also describing improved mood. When asked about how the treadmill desk impacted their work, 11 participants described feeling more engaged or more satisfied with working from home, and 6 participants felt more productive. Socially, all 20 participants recommended a treadmill desk to others, and nine participants found it to be a topic of conversation with their coworkers.

Motivators

Participants found motivation in health and fitness benefits, through tracking and reaching their goals, and from knowing that it would feel good to walk while working (see Table 4). Fourteen participants were motivated to reduce prolonged sitting and be more active, and 13 participants aimed to be healthier and more physically fit while avoiding ill-health:

Wanting to be as active as possible is a motivator. I know that exercise is important. I know it's important to avoid prolonged sitting, you know so that encourages me to kind of get up and get on there. (Participant 1)

Table 4 Theme: 2.0 Motivators

Eight participants described aiming to walk 10,000 steps per day and using technology to track outcomes such as step counts, distance walked, or calories burned. Five participants were motivated by pain reduction and the joy of movement. Eleven participants were motivated to obtain and use a treadmill desk due to the COVID-19 pandemic.

Barriers to Use

Barriers to use were more commonly due to the type of work being completed and social concerns (see Table 5). Nine participants described not walking while engaging in tasks requiring greater cognitive effort, such as writing or switching between different work tasks:

And then I've found that there are certain tasks that I was able to do really well and I would, you know, I wouldn't even realize how long that I was walking on there, so it would be like um reading things or doing like data entry. So if I just had to, you know click one or two keys on the keyboard I could do that, but when it came to like really focused writing, so when I you know, having to use a full keyboard or having to really do like effortful thought, that's when I realized like I couldn't, I couldn't do that as well while I was walking, and I would need to be sitting for that. (Participant 4)

Table 5 Theme: 3.0 Barriers to Use

Eight participants did not like to walk while engaging in fine motor control tasks involving typing or precise mouse control, and another eight participants did not use their treadmill desk while presenting or in meetings, especially if they were on camera. Physical, mental, and accessibility barriers were less common. For example, fatigue or illness were described as physical limitations by three participants:

I would say the only thing is like I said, I can really only tolerate it for about 45 minutes. It just gets to be too tiring and so I'll stop and rest and you know, sit down. (Participant 16)

Possible differences in perceived benefits, motivators, and barriers to use were explored by gender, age, length of treadmill desk ownership, and treadmill desk use (hours per week). The results of this analysis are presented in the Online Resource, Tables S1-S3.

Discussion

This study has contributed novel findings to the literature on active workstations by being the first to describe treadmill desk use at home. In response to RQ1, we found that our sample of treadmill desk users was comprised of predominantly white, middle-aged, married women who lived in suburban neighborhoods and held high-income, full-time, office-based jobs. The majority had purchased a Lifespan treadmill desk themselves which they kept in their home office. Most participants worked fully from home and reported a shift to working from home due to the COVID-19 pandemic. Participants used their treadmill desks for about two hours per day, picking a speed at which they could walk comfortably and complete their work or non-work tasks.

In response to RQ2, the physical, mental, work-related, and social perceived benefits experienced by the treadmill desk users align with and expand upon previous experimental and qualitative literature on the benefits of treadmill desk use. For example, past findings indicating that participants are more active, lose weight, have more energy, better focus, more positive affect, more task satisfaction, and feel less stressed when using a treadmill desk as compared to sitting or standing were supported (Cifuentes et al., 2015; Giumetti et al., 2021; Sliter & Yuan, 2015; Thompson et al., 2014). However, past research has not demonstrated any changes in physical symptoms, like back pain, when using a treadmill desk (Giumetti et al., 2021), whereas six participants in our study described the relief of joint pain as an important physical outcome and a “game changer”. Another novel finding from our study was that nine participants described cardiovascular or fitness improvements that translated well into their other physical activities. Furthermore, three participants described improved creativity while walking, which has been demonstrated in past research on walking (Oppezzo & Schwartz, 2014) but not in the context of using treadmill desks in the workplace.

Past within-subjects experimental research did not find support for increased job satisfaction at the end of the workday when using a treadmill desk across three 1-h walking sessions compared to three 1-h sitting sessions (Giumetti et al., 2021), but 11 of our participants described treadmill walking as improving their satisfaction with working from home. Additionally, while walking on a treadmill did not improve brief task performance compared to sitting and standing in a 30-min within-subjects experimental session (Zhang et al., 2018), six of our participants described feeling more productive when using their treadmill desk. Importantly, the current study did not use an experimental design and therefore cannot establish a causal relationship between home treadmill desk use and job satisfaction or productivity. Our findings may be different from the findings of Giumetti et al. (2021) and Zhang et al. (2018) due to many factors, including the qualitative nature of our data, our participants' long-term experiences using a treadmill desk at home, or even our participants' desires to report positive outcomes of their treadmill desk use.

A unique and surprising finding was that one participant felt that their treadmill desk helped them have better work-life balance. Interestingly, this is supported by the finding that taking more steps before the end of the workday is associated with greater satisfaction with work-life balance (Calderwood et al., 2021). Our interviews also revealed that seeing a coworker use a treadmill desk can serve as a social contagion for obtaining and using a treadmill desk of one’s own, which is aligned with past research demonstrating that coworker social support is positively related to physical activity in the workplace (Sarkar et al., 2016).

In response to RQ3, our interviews revealed that participants were motivated to use their treadmill desks to reduce sedentary behavior. For many participants, this was in response to increased sedentary behavior brought on by working from home during the COVID-19 pandemic, and this increase in sedentary behavior is supported by past research (Howe et al., 2021). Participants also wanted to be healthier, avoid health problems, and lose weight. These health-related motives are common amongst middle-aged and older adult cohorts (Box et al., 2021). Eight participants also described being motivated to reach step goals, and two participants competed against others to take the most steps. Past research has shown that a workplace-based challenge to walk 10,000 steps per day was very successful at increasing daily walking behavior in working adults (Vandelanotte et al., 2020). Another motivator for treadmill desk use was the anticipation of the perceived benefits like feeling good due to alleviation of pain, enjoying movement, or overcoming afternoon fatigue, which is supported by previous research indicating that feeling good and exercising comprise a positive feedback loop (Emerson et al., 2018).

In response to RQ4, our interviews revealed that many of the barriers to using a treadmill desk at home were similar to barriers experienced by treadmill desk users in the workplace, such as the type of work being done, difficult set-up, back, knee, or leg problems, the treadmill being noisy, interruptions from others, and concerns about coworkers’ perceptions (Cifuentes et al., 2015). Some of these barriers to use were unique to working remotely in our sample, such as concerns about how one appears while walking during a video call. Interestingly, previous research indicates that common barriers to physical activity in the workplace are workload and time constraints (Mazzola et al., 2017). However, in our study, having access to a treadmill desk at home enabled participants to overcome these barriers by offering light physical activity while working.

Study Limitations

A limitation of the current study was that we did not use a random sampling method, but rather enrolled participants that responded to our study advertisement. It is possible that individuals who responded to the advertisement felt more positive about their experiences with their treadmill desk than those who did not respond, which may have contributed to our findings on the perceived benefits of treadmill desk use. New treadmill desks also can be expensive, with prices currently ranging from about $250 to $3,000. Due to this expense, participants may have been biased to perceive benefits from treadmill desk use.

Another limitation is that participants were not randomly assigned to treadmill desk use, but rather had purchased their treadmill desks for themselves, suggesting that they may have sought their treadmill desk specifically to reduce sedentary behavior or alleviate pain. Additionally, because our study examined treadmill desk use at home rather than at the workplace (Cifuentes et al., 2015), we were able to identify novel perceived benefits, motivators, and barriers. However, our sample was rather homogenous demographically, being composed of mostly White women with high incomes. As a result, our findings may not generalize well to other gender identities, people of color, or individuals with lower incomes. Our small sample size also limits our ability to make conclusions about differences in perceived benefits, motivators, and barriers to use across demographic groups and features of treadmill desk use.

Future Research and Practical Implications

This is a preliminary study on treadmill desk use at home, and future quantitative and experimental research is needed to confirm the findings of this study. Additionally, future research on effective interventions for increasing treadmill desk use at home are needed. The information about motivators and barriers to use from this study should be helpful for intervention design, although a future study on individuals who own treadmill desks but do not use them could provide further ideas for intervention strategies. For example, a future intervention may focus on the health benefits of treadmill desk use and provide participants with opportunities to track their step counts. Interventions tailored to an individual’s primary exercise motivations may also be effective, such as a step count competition for those who enjoy the competitive aspects of exercise. Future research could also explore if providing walking prompts and performance feedback would help to increase treadmill desk use (Batchelder & Washington, 2021).

Practically, this study provides further evidence to employers that treadmill desks have a host of positive physical, mental, social, and work-related perceived benefits. Employers can support employees’ use of treadmill desks when working remotely by providing financial support for their purchase and positive reinforcement for their use during the workday.
