We all know cardio is the magic bullet against weight loss, no doubt. But i'm in a pickle. I was doing some bike work for a few hours a day until my left knee gets this crazy ass sharp pain for no reason. It acts up when I get on the stair master, the elliptical, upright and seated bikes, and treadmill. I rested it for a week and it came back after a light jog and that was with 10 minute stretching. Hurts a ton, but regular short walks is fine until I get 15 minutes into it.
So what else can I do, exercise wise, to lose weight? I know diet is the second half of the story but i'm taking in 2kcal at 5' 6" 168lbs and lifting regularly. I got no fat except around my damn belly =(
