Hi Cathe and educated crowd. I did GS legs for the first time yesterday, and I have a form question about the barbell stiff legged deadlifts on high step. As with the regular stiff legged deadlifts, do I keep my shoulders pressed back so they dont roll forward. It looked like Cathe was extending her shoulders at the bottom of the move to reach out and beyond the step. If I keep my shoulders pressed back, I can't reach the barbell down to level of the step and I am not sure I am getting the maximum benefit of the exercise. Also, should my legs stay locked straight or slightly bent at the knee and does it matter? I would be very thankful for form pointers on this specific exercise off the high step. Thank you.
