Input:
This band is great for P90X workouts.
I use it for anything light, like shoulders and triceps.
If you make a loop and step on it, it can give you more than 20 lbs of resistance.
I also have the extra heavy one, for back and biceps.
They work great, easily portable, and cost WAY less than a single pair of dumbbells.
