Camel

Stand on your shins with your knees hips-width distance apart.
Exhale to lean back, and place your hands on your heels, arching back and allowing your head to fall between your shoulder blades.
Hold for one breath, then use your abs to lift your torso up. Repeat four more times.
On the last one, hold Camel for five breaths, focusing on pressing your hips forward to engage your abs, thighs, and glutes.
