People still listed to the prodigy? haha j/k I prefer Disturbed, basically the whole "Down with the Sickness" album when I work out. Funny thing is I'll listed to Norah Jones when I snowboard...don't judge me.
Anyways, you're on track with the deep knee bends, basically one leg squat into runners stance and back up, 20 reps then switch legs. Then wall sits.
Here is a guy with his shirt off jump roping, is that better? bwahahaha
