Standing with feet hip-width apart, hold the barbell at chest height with palms facing up and your elbows extended out in front of you. Keeping the barbell rested at your chest, squat deep. In one explosive movement, push up into standing, tilting head back slightly to surge the barbell straight overhead so knees and elbows are both locked straight. Lower barbell back down to shoulders and repeat.
How to do medicine ball burpees: Standing with your feet shoulder-distance apart, hold a medicine ball with both hands. Extend the ball up overhead, then slam the ball down on the ground as hard as you can, hinging over and sitting your butt back as you slam. As you hinge over, bend your knees. Place your hands on the ground outside of your feet and jump back into a high-plank position. Keep your body in a straight line. Then, jump your feet back towards the outsides of your hands so that you are squatting. Pick up the ball and press it overhead, extending your body and standing tall.

Consider it a good excuse to pick up that hobby you've been eying.
