How do you do stiff legged deadlifts that focus on the back and not the hamstrings? Do you start from the top, go down to parallel, then go back up?
It's all in the technique, your legs will get worked aswell but this is great for lower back growth
Start by standing straight up, keep your chest high, abs tight and knees slightly unlocked, bend forward at the hips, letting the bar naturally track away from your body.
Allow your low back to round slightly as you go down.
Pause when you feel a good stretch, then reverse the motion by contracting your glutes and hamstrings, allowing the bar to come closer to your body only as you approach the starting position.
Squeeze your abs, back and glutes at the top.
