Barbell skier

Stand with your feet shoulder-width apart and hold a barbell in front of your thighs with an overhand grip. Bend your knees slightly and hinge forward at the hips, keeping your back straight and chest up. Simultaneously lift the barbell up towards your shoulders while jumping slightly off the ground. As you reach the top of the movement, quickly reverse the motion and lower the barbell back down to the starting position. Repeat for the desired number of repetitions.
