Time: 30 seconds
How to do it: From a plank position, step your left foot outside of your left hand. Jump off the ground, piking your hips up in the air, and switch legs, landing in a lunge position with your right leg outside of your right hand. Continue switching sides as quickly as you can for 30 seconds.
Form tip: Keep your arms strong and your shoulders positioned over your hands during your jumps. If it’s too tough to jump, simply step into the lunge position from your plank, switching sides quickly.
