I was having a problem with balance to begin as well. Not that I'd fall over, but that stepping back up was an exercise in trying not to wrench my knee out of its socket. It's a little off plan, but I started doing stationary lunges - step forward once and then just lunge up and down for all reps, then step back. I finished Stage 1 and 2, then moved to Fat Loss 1 from NROL where we're doing sets of 15 lunges to start, and I find I'm much better at them now.

I don't think it would be cheating to do them next to something and reach out if you start to lose your balance. Don't be afraid to add weight either, but don't add weight if it makes you lose form, either.
