The P90X Fat Man

Swash, I'd say you're right. Muscle confusion is happening. Your body is trying too make sense of everything that you are doing, and you keep changing it up so it can't become complacent. So your muscles are recovering from your previous workouts and they still are probably carrying lactic acid in them. That would be the achy muscle soreness. DOMS = delayed onset muscle soreness. Which, in my experience, can cause balancing issues, especially when using the quads. Your legs are tired, then you tell them you are going to balance on them and try and go inverted into a half moon? my legs just laugh at me (still). I do those close to a table, so I can throw out a hand for balance if/when my legs try to gigglesnork when I try those moves.

but man, I love the feeling of DOMS. as much as it hurts. I know I've done some good work on my body. It tells me that i've broken down more muscle, and that builds even more muscle, which in turn burns more calories when I'm at rest.

I do hope that your shoulder feels better soon.
I'm doing my cardio tomorrow (day 6, as I had to flip my rest day to today-son's hockey tournament) not sure if it will be kenpo or another kickboxing dvd that i'll use....

have a good rest/stretch day tomorrow!

congrats. well done

Good job.... watch out Phase 2 here you come
