Start with your forearms flat on the ground, body facing the ceiling, and feet planted on the floor. Make sure your elbows are directly under your shoulders, your hips are tilted towards your ribcage, lower back glued to the ground, and knees bent. Lift one leg off the ground and your foot out (the arch of your foot should be facing the ceiling, kneecap facing the side). Keep the bend in your knee as you gently lift your leg to your highest point without losing the tilt in your hips, then back down – hovering slightly off the ground. Keep your belly button cinched to your spine and complete 12 lifts with one leg, then switch legs to complete 12 on the other.
