HOW: Place a barbell in a landmine and stand at the end of the barbell. Shift your weight to one leg, slightly bend the knee, hinge at the hips and reach down and grab the barbell end. Pull the bar up using your hip and then return to the starting position and repeat.
FEEL: You should feel your hamstring muscles working while balancing. You should also feel your glutes and low back working.
COMPENSATION: Keep your back flat and just a slight bend in your knee at all times.
