Cooldown: Lying Knee to Chest Stretch Lie on your back with your legs extended. Gently bend your left knee into your chest. Clasp your hands in front of your shin and gently pull down to increase the stretch. Release any tension in your shoulders and neck. Keep your right leg relaxed in a comfortable position. Hold for three sets of 15-second holds. Image Source: POPSUGAR Photography / Louisa Larson
