When learning this exercise make sure you use good form.

Always start with the bar.

Keep your reps high at first until you get used to the movement, then you can start lowering the reps as you get stronger at this exercise

Each week add small amounts of weight making sure that you can handle it easily.

After a few months start to push yourself harder and harder, adding more and more weight.

This exercise will build a great deal of strength right through your calves, hamstrings, glutes and back.

Execution

Place yourself under a barbell as if you were going to do a squat, keeping the bar high on your traps

Step back with a narrow stance.

Lock your knees in a slightly bent position so you don’t put to much stress on your hamstrings

Keeping your back in its natural curve begin to bend forward with your hips/waist until you are roughly parallel, then return.
