The healthy back workout

Floor twists
Lie on your back and bring both knees up to your chest. Place both arms outstretched on the floor at shoulder level, palms facing the floor. Keeping both knees lifted, gently move them over to the right so that your right thigh is touching the floor. Look to your left side and try to keep your left shoulder from lifting off the floor. Hold for 30 seconds and repeat on the other side.

Child pose
From an all-fours position on the floor, bring your bottom back and nestle it down on top of your heels. Stretch your arms out in front of you along the floor, and try to keep your elbows pressed into the floor and your chest close to your thighs. Let your forehead touch the ground, relax and hold for 20 seconds.
