DO IT
This app is life changing. saw it on an add on Facebook and decided to give it a try. The trainers are motivating and push you to your limits. With all the different levels, anyone can use it (and modify if needed). I find myself anxiously awaiting my workout and constantly checking the app to decide which workout Im going to do. Try it, you wont regret it!
