I was all excited today I did my insanity workout without a jiggle. I broke down and bought one of those Under Armour sports bras, a compression tank, compression shorts, and put that on under my normal workout clothes. Not a single wiggle and my back does not hurt. I was really impressed with the sports bra. I was a skeptic spending so much on a sports bra but in the end it was really, really worth it. The sports bra and compression tank and shorts kept the wiggles in line so I could finally give insanity my all.
I also took back the Reeboks I totaled last week and bought a new pair of Asics today that I love.
Great workout today. Thanks for all the advice.
