Re: INSANITY
Insanity has been awesome. I travel 4 days a week and need something I can do in the hotel room. I carry a monitor cable in my bag to hook up to the TV. I've dropped about 15 lbs (although 2/3 of it muscle) and just feel better.
I've been working out for about 15 years - football, track, hockey, etc and I don't know of a better, more compact and effective 30-45 minute workout.
It is tough to stick with it, but if I am going to work out at all, this is one of few options for me (alternatives include 1/4 mile sprints on the treadmill followed by 50 pushups, sprint, 50 lat pull downs, sprint, 50 situps, sprint, 50 squats). Jump rope / push up combinations also work.
