plough pose
Lie flat on your back alongside your child on a yoga mat or on a carpeted floor. Your arms should be at your sides with your palms facing down and your fingers pointing toward your toes. On the inhale, zip your legs together and, using your core, bring them up at a 90° angle, keeping them straight, with your toes pointing toward the sky. On the exhale, fold your legs over your upper body, reaching your toes toward the floor. You should be looking at your knees. Again, keep your legs straight. On the inhale, roll yourself back to the previous 90° position. On the exhale, slowly lower your legs down to the ground. Repeat 4-5 times, slowly with the breath.
This is a wonderful core strengthener and helps you to align your spine.
