Attach an empty barbell to a landmine or wedge one end of the barbell in a corner.

Get down on your hands and knees, and wedge the barbell between the lower hamstring and upper calf.

Steadily lift the right leg up until the thigh is parallel with the ground, focusing on the right glute doing all of the work. Pause at the top for 1-2 seconds.

Slowly return to the starting position.
