Well I tried the arms and abs circuits about 2 hours ago. Arms are still a bit shaky, yay! Usually I do a free weight arm circuit, so this was a nice change. The ab workout is awesome. I made it up to 12, and then had to stop after 8 going back down. :oops: Out. Of. Shape. I'm determined to get all the way back down though! I also sent the circuits to my ex-bf who's a personal trainer/group ex instructor and he loved it and is going to try to incorporate it into his classes! Didn't do the leg one for a couple reasons a) I ran this am, and b) I'm pretty sure I'd get some strange looks if I was cheetah-hopping around the gym haha. We'll see how sore I am tomorrow, but for now I feel great!
