Medium width, high foot placement, knees at least to 90 degrees, leg presses. Deep squats (past parallel). Also started using cables on the one female client I'm preparing for a show. Face the weight stack, attach an ankle strap to the low cable, knee joint at about 135 degrees, then kick back to straighten the leg and pause and squeeze the glutes and hams at the top. Replicates a butt blaster movement. Really hits the glute/ham tie-in. When flexed at the top, you can see the glutes and hams just pop out.
