P90x2, balance and power...week one done

I just finished the Balance and Power workout. Like most of the others in Phase one, there is not a lot of explosive movements, but what are are doing is made very hard by the fact that you are doing it on a stability ball or medicine ball. Most of the moves in this workout are done on a stability ball. The hardest ones for me are moves where you have to put nearly all your weight on the ball (like the sphinx to plank) moves, because it really wants to roll around on you. It is a fun workout but will provide quite a challenge unless you have done a lot of balance and stability workouts before. I found myself using very light weights for the moves that required weights. I pretty much stuck to the 10-12 pound range. I think that is important the first time around because until you learn the moves well it will be really easy to hurt yourself if you try to be a hero and go too heavy. I'll be posting a progress pic tomorrow on the message board thread I set up on team beachbody. It is linked from one of my other p90x2 posts. If you feel so inclined you can jump over there and check it out. Thanks for reading!
