I did it just like it, or tried anyway. And my shins and lower thighs were pretty raw after the session so that's some biofeedback telling me I did something right (obviously not everything). The problem is do to especially weak hammies and somewhat weak quads while having relatively strong hips and back. Time to work in some deficit work and focused hamstring supps.
I'm thinking sumo and conventional deficit deads, some band dead's to help explode off the floor and front box squat. Work on sldl's with more focus on the mind-muscle connection to my hams than the weight, band leg curls, narrow high leg presses. No access to ghr and tried them in the lat pull down machine with no luck. Maybe some narrow stance, toe elevated gm's.
