"Lie on your back with your knees bent and feet flat on the floor, hip-width apart. Position your heels so they’re about a hand’s length away from your glutes. Keep your arms at your sides with palms down. Brace your core and keep your chin slightly tucked."
Key point: “Your feet should be close enough that you can push through your heels without your toes lifting off the floor.”
"Press through your heels to lift your hips toward the ceiling until your body forms a straight line from your shoulders to your knees. Squeeze your glutes hard at the top without overextending your lower back. Lower your hips under control back to the floor and repeat."
"Inhale as you lower your hips, exhale as you drive up and squeeze at the top."
