Warm your muscles up with some brief cardio like running, jumping rope, or doing jumping jacks. It’s important to warm up your muscles before stretching to avoid strain and potential injury. Before trying to touch your feet to your head, stretch your hamstrings to avoid straining them.  Sit upright on the ground with your legs held straight in front of you. Slowly bend forward at the waist, keeping your back straight. Extend your hands and reach for your toes. If you can’t reach your toes, try touching your ankles or perhaps your knees. Move your extended legs out so that they’re about shoulder width distance apart. Repeat bending forward and reaching for your toes (or ankles or knees). Begin by sitting on the ground with your legs extended in front of you.  Bend your right knee and bring your right foot inward towards your pelvis. Slowly bend forward at the waist, keeping your back straight. Extend your left hand towards your left foot; try to touch your toes. If you can’t reach your toes, try to touch your ankle or your knee. Repeat each step on the left side. Warm up your back with some gentle stretches so you don’t strain it.  Start on your hands and knees and slowly drop your head and pull your back up into an arch. Hold for several seconds. Drop your stomach, lift your head, and pull your back downward into an inverted arch.  For the next stretch, lie on your back with your knees bent and your feet on the ground. Keeping your back on the ground and your legs bent, slowly lower your knees to the ground on your right. Move your legs back into a neutral position. Repeat the stretch on the left side.
