Anybody use the Spinervals strength workouts? I just got the leg conditioning/building one last night but thought that one looked nice. I've considered Strendurance but just can't tell enough about it or the other ones (Iron Girl and the Ultra Conditioning series) to know if they are good. From the clips, it looks like the form isn't always the best and the speed fast. I am completely addicted to the Spinervals bike workouts and wouldn't mind adding some of their strength ones if they are worth it. Thanks in advance
