Only been doing this app for a month. Decided to try it to get me back on track with exercising after an injury this summer. Its been great, only using the free work out so far. It has definitely been getting me motivated with the reminder to get at least 1 workout in during the day. I have already noticed a difference in my ability to do the exercises, and Im looking forward to unlocking more exercises. I would encourage anyone to try it. I have not had any problems so far with the app not working correctly.
