I have only had this app a week. Having the option to work out with/without equipment is great. For me the only thing I needed was the resistance band. (Inexpensive) though I started with the full body workout, if I feel I want to work on my legs during break at work thats all I have to target. Liking a lot so far. Will love it once I see results. I will also wrote a review in a month or so..
