I think I started to get a hang on Legs & Back, but still stumbled a lot when doing the balanced lunge and the 3 direction lunges when you have to do the kick after coming out from the lunge (dunno the exact name, sorry). The resistance band is pretty useful as a substitute from the pull ups. However, maybe I didn't pick the right band or I did it wrong...no way I can do 20 reps while Sophia girl could only do 15 reps max.
I don't have any high chin bar on the ceiling, so I just wrapped the band around the handrails of the stairs.
Abs was good...I could at least complete most of the reps without problem.
