intriguing....
what are some explosive quad-dominant ideas -- aside from something using a machine (everything's too spread out, so throwing a machine in would defeat the point of a superset).
I train hams all the time; but avoid many quad specific exercises because I don't want bigger quads (or calves, for that matter). for quads, I've been throwing in fast, high box squats every other week (hits the quads most and forces the use of more stabilizers, unlike leg press); but that's about it (aside from the ways quads are involved in other lifts).
