I did mine last night, still hanging on for dear life in group two. The first 4 sets went okay, then I got to the max out. Oh my that was awful. I am doing the knee push-ups and it is not that much easier. Sure I can do more but my muscles are sore this morning anyway. I am on a W-F-Su schedule again this week, I was hoping Tu-Th-Sa but alas it is getting harder to get moving on these things!
