Shoulders and Arms and Balance

Hey fellow P90x2ers! I just did the P90x2 Shoulders and Arms workout for a second time. As I mentioned last week, I LOVE THIS ROUTINE. However, last week I did the workout with resistance bands. This week I did the routine with weights. I have a few different color resistance bands that I use but I think this routine works best with weights. I felt like I could really work on my balance while using the balance ball with weights instead of using the resistance bands with a foot in the air. It felt less stable but I felt more in control. If that makes any sense. Personally, I think some workouts are just better with the bands while others are better with the weights. I like that I have both and can choose which works best.

What do you use . . .Weights or Bands?
