I felt I got a much better workout on my arms and shoulders this time around. Last time I only had 5lb weights and it didn't feel like enough, so I bought 8 and 10 lb weights. I'm not strong enough for the 10lb ones yet, but most of the moves I was able to lift 8lbs. I have to go to the 5lb weights for triceps though. I think I'm going to be sore tomorrow!
I'm still having some trouble with the Ab Ripper. A lot of the moves hurt my back, especially the ones where you start from lying down and have to roll all the way up to touch your toes. Ouch! So I've been doing a lot of modifications on this workout. I also think it will be a while before I'm able to do 25 of any of the exercises!
