LOL-Women Rejoice- Dynamic Inertia is here to make you fit

sorry if it has been posted already..

here we have the revolutionary Shake Weight Exercise for women "Dynamic Inertia" :P

Lulz

I smiled at it.

lmao, too funny.

Talk about making women look stupid

ROFLyoutube comments are always funny

Funny... those resultant arms looked just as "bulky" as those you'd get doing weight training on machines (the only reason they don't in the video, is because they use a male body-builder as the "example"). Any kind of strength training will produce the same results. If you want slimmer arms, do more cardio.

I think it's funny how they are trying to indicate that bulky muscles are bad. It's like, "Hey woman, you don't want to have muscles. They are bad!"
