Hey! I have purchased a couple of I Strength workouts, and yes, they are geared for the gym. I find them very difficult to use - the cueing isn't so great, and you need to be able to get to the equipment you need quickly. The ISculpt workouts are great once you get the hang of them - Grace works your butt off!! ITread is good, too, although her speeds are a little fast for me - I'm short and can't run/jog as fast as her 'numbers.' They are good for on the road!!!
