i felt it....a little. it's a good idea...but i don't think it's super challenging...weighted maybe....i'd like to try out the swiss ball with water in it idea too.

i also tried the superdog...and....eh.

i like his stuff most of the time...it's very "common sensical"...the only thing i didn't agree with was his shoulder posture blog entry about how we keep the pelvis in neutral but not the shoulders. i personally like my shoulders back from neutral all the time, just to be sure my RC tendons have enough space. i'm even anal about it while sleeping

the cool thing about the tight rotation was...with shirt off...looking in the mirror....i could see each side of my abs "activate" and then turn off, etc.
