But knowing I had to keep shifting it, I decided to dig deeper into the well and vary my workout a bit, focus on a different muscle group. The majority of the stuff I've done so far is upper body, and I was worried I'd overdo it or forget the rest. Last week I did a bunch of lower body stuff in the gym. I was rusty at it, but made it through.
Last night I moved on to the next P90X thing, which was called Ab Ripper X. 15 minutes of crunches and related moves.
I could barely do any of it.Crunches always suck, but what surprised me when I tried it was how much the moves hurt my lower back. I couldn't focus on the crunch because it hurt just to sit or lie in the correct position.
I haven't figured out why this is - or what's wrong with my back (it doesn't hurt at other times), but I had to shift focus and decided instead do do a bunch of the Turbulence Training full body exercises instead.
The book should arrive soon. We'll see if it helps.
