Last night I had a soccer game so I skipped my P90X workout. This evening I did the cardio X workout and it went really well. I started off wearing my back brace, but ended up taking it off because I didn't need it. I felt I was able to do a better job with the workout this time around too. I like this workout, mostly because it's only 45 min!! I think my favourite move is the wacky jacks. I always start them off wrong, but once I get the hang of them, their fun!
