Hello! How are you feeling? As long as you're walking you're moving and letting your body heal. X52! Maybe you need low impact to see if that helps your back? I had some hip pain yesterday after Crossfire on Tuesday-enough that I vowed (again) that impact wasn't worth it if I locked the joint. So, I stretched and went to the pool and it's fine today, but it scared me yesterday.
Today I'm doing Push/Pull from BB Series. It's 45 minutes total body and since I'm in a work stretch, 45 minutes sounds good! My latest schedule is: Mon/Thurs-Total Body, Tues/Friday-cardio, Wed.-pool, weekend: one day rest, one day what I feel like doing: bike, pool, walk, whatever.
