so ive been doing the insanity workout lately and i was wondering if anyone else has done this and what they thought. All it really seems to be is cardio i did p90x for a bit and that atleast seemed to be more with weights and gave you more of a workout instead of just running. ive had to do these because the closest gym is about a 45 min ride but finally one is in the process of being built nearby and should open soon. anybody have any ideas of good workouts you can do in a house with only having dumbells?
