That said, we do plan on writing apps for both iOS and Andriod so you can take it with you to the gym if you would like to. It's not JUST body weight exercises though and we have exercises for dumbbells and exercise bands (things people are likely to have at home). And we do plan on adding exercises that incorporate gym or home gym equipment as well.
The advantage over something like p90X or Insanity is that these workouts are customized for you based on your current fitness levels and your fitness goals by an actual personal trainer. Every workout is unique and different so you're not doing the same thing week in and week out. It's not just some generic program that is the same for everyone who is doing it.
