Begin on all fours with your hands directly below your shoulders and your knees beneath your hips. Keeping your core engaged and your back flat, lift your knees so they're hovering over the mat.
Lift your right hand and left foot off the floor, simultaneously turning your torso to the right and kicking your left foot underneath you and across your body.
Continue to swing your leg all the way through, pivoting on your bottom left hand and bringing your right hand toward your chest. Make sure to keep your core braced throughout. Take your time; this should all be done in one fluid movement.
Spin back toward the ground, placing your right hand and left foot back on the ground as you return to the starting position.
Repeat on the other side, lifting your left hand and kicking your right foot through.
This counts as one rep. Complete as many reps as you can with proper form for 45 seconds, followed by a 15-second rest.
