Curse you Jillian Michaels!
I've been doing the 30-day Shred for about 20 days now and I've loved Level 1 and 2. I lost about 8 lbs, and I dropped down to a comfortable size 14 (haven't seen that in over 17 years!). But I tried Level 3 yesterday and I'm having trouble with it. I broke my arm a few months ago, and had surgery to put everything back together with plates, screws, etc. I don't yet have my full strength or range of motion back (and probably won't for about a year). So, all of the push-up and plank type moves in Level 3 are a killer for me - my wrist just won't bend that way and my arm won't support it yet. Grrr - I really wanted to finish the whole thing, but it looks like I'm back to Level 2.
