Well just about every single leg exercise I do has some form of hip extension so the hams get hit hard - full squats, oly lifts, oly style pulls, deadlifts/rackpulls - all types, weighted hyper extensions (get your hips as much off the pads as possible and hams will get hit hard!) , reverse hypers (bodyweight mostly), and I also do glute ham raises on the floor - very rarely these days though.
vert is estimated to be above 36 inches, it would be much higher if I leaned up a bit - 10lbs could make quite a difference
But damn am I so much faster now!
