LOVE the power drills!!!! Boy, they will get ya if you really are intense with them the first time. I had been lifting with Cathe for awhile when I first did CK. I gave every drill my all. I could barely move the next day. My back, shoulders, biceps...all toast. Remember when Cathe starts screamin' out "Do you feel it...back..shoulders....tri's...EVERYTHING!!!!!!!". I always think of my very first time with CK when she says that!!!
