Stand with your legs at shoulderwith, or togheter. if you are flexible, stand on an elevated paltform ,so the weights dont touch the floor. grab the bar, with a shoulderwith grip. bend forward, back straight, slightly bend in knees. go as far as you can, then lift up with your back and hams, when you almost reach the top, straighen you knees and flex your hams. you should feel it in your hams, butt and lower back...you dont have to go heavy on this exercise..you wil lfeel it no matter what
