Interesting.
One thing I've found out is that if I do a side plank, with the free leg and arm elevated (so basically, a star shape in a side plank position) my glutes feel extremely "alive" after that and I walk "funny" (like more on the toes). I'm not sure what's up with that, it always does that when I do them. It's probably the gluteus medius being activated or something, not sure if it's the gluteus maximus there, but still, walking feels so much more hip dominant. Not sure about jumping, I need to try that a few times and see what happens.
