Saturday I had my best cardio workout since my ACL operation. I went to my gym and, after pushups, situps, crunches and some s-t-r-e-t-c-h-i-n-g, which I haven't done often, I tried out the rowing machine for 10 minutes, then went on the elliptical for 20. It felt really good.
I've gained about 8 pounds since the operation, but now I can start upping the cardio workouts, I hope that will burn off some of the weight.
Today, after chores, I want to do some physical therapy homework (mostly involving bending or slowly torquing my left knee with weight on it) and then some shadow boxing and a bag workout. I've got a little bag in the basement--I would guess 50 pounds. It's not long enough to do kicking and punching (I mostly kick low, due to flexibility issues at my age, but also since I don't want people catching my leg in sparring). Heck, I can't do much kicking yet anyway. But my sensei said to start using the bag for punches, so I've been trying to do so. (The first time, I realized how unconditioned my hands had become to punching a bag, even with wraps and gloves on.)
