Okay! I just finished Pyramid Upper Body and I have to say that it is a very refreshing change. This was my first time doing a pyramid-type workout. The exercises move quickly with little or no rests between sets. This is the perfect workout for the winter blahs! The only push-ups in this video are done on your knees in the warm-up. The stability ball work is very challenging. One move is bringing the ball forward from a lying position and kicking it two times quickly, then you go all the way back and come up in a half-crunch. The Pike is also included. That's a move where you start out in a straight-armed plank position on the ball and bring it in with your feet, keeping your legs straight. There are no traditional crunches. This video flys by so quickly that you almost feel like you cheated and didn't get a full workout in, but your shaking arms know better.
