Jumping Box Muscleup

Set up a box underneath a pullup bar where the majority of the box is behind the bar as opposed to being in front. Stand slightly behind the bar. Grab the bar with the arms about shoulder width apart. Bend the knees and hips slightly to get some momentum and jump up flipping the elbows and shoulders over the bar and using the triceps and chest to hold yourself up with straight arms. Lower yourself back down until your feet rest on the box. You can make these easier by using a taller box, adding bumper plates to the box you are on to find the perfect height, or by squatting down lower to get more “jump” assist into it.
