Start by placing your forearms on a yoga mat and extending both of your legs behind you, resting on the balls of your feet. This is your starting position.
On an exhale, lift up your right forearm, placing your hand firmly on the mat directly below your right shoulder, and push up onto your right hand. Lift up your left forearm to place your hand firmly on the mat directly below your left shoulder, and push up onto your left hand. Ensure that you keep your core engaged to prevent your hips from swaying.
Inhale, and lower your right forearm to the mat, then lower your left forearm to the mat, returning to the starting position.
Repeat this exercise starting with your left arm.
Continue alternating between left and right for 40 seconds, then take 20 seconds of rest.
