Home-based Resistance Training for Adults With Severe Obesity

"Patients completed two home-based resistance training sessions each week on non-consecutive days for 12 weeks. The programme was delivered online via individual playlists on Youtube (YouTube, San Bruno, California, USA), with each playlist involving an individually-prescribed series of pre-recorded exercise videos. Each session involved a dynamic warm-up followed by 11 resistance exercises using body weight and resistance bands, and finished with static stretching. Participants completed 1-2 sets of 5-12 repetitions at 4-7 on a modified 10-point rating of perceived exertion scale, which corresponded to qualitative descriptors of moderate to hard. Resistance training stimuli were progressed weekly by increasing the external load, modifying the exercise selection, increasing the number of repetitions, and/or increasing the number of sets."

After the initial baseline assessment, participants recorded the number of steps they walked daily for seven days using a waist-worn pedometer. Participants maintained their usual physical activity levels during this period. Participants were then encouraged to increase their total steps walked each day by 5% each week during the 12-week intervention.
