Warrior.

Tones your thighs
Strengthens your core
Stretches your chest, hips, groin, abs, and shoulders

Many people allow their torsos to collapse forward in the Warrior pose. Holding the ball overhead will help you keep your torso upright and your chest open, allowing you to feel a deeper stretch in the front of your hips, your abdomen, and your chest.

A. Stand with your feet under your hips. Hold the ball overhead. Exhale as you step forward with your left leg. Inhale and lift your right heel and move it inward so that your rear foot is at a 45-degree angle.

B. Exhale as you bend your left leg and sink into a deep lunge, as shown. Keep your upper arms in line with your head and reach up and into the ball, as if you were Atlas holding up the world. Hold for 30 seconds, breathing normally. Inhale as you rise to the starting position and then repeat on the other side.
