Stand tall with your feet a few inches apart and parallel. Bring your palms together and hold them at your heart. Inhale and lift your arms overhead, keeping them shoulder-width apart and your elbows straight but not locked. Look directly ahead or up slightly (shown). Exhale and lower your arms as you bend forward from the waist, bringing your chest out and down and as close to your knees as is comfortable. Bend your knees slightly if needed, and stretch your hands toward the floor. If you’re especially flexible, you can intensify the pose by pressing your palms to the floor and straightening your legs. Inhale and return to standing. Lift your arms overhead and gently lean back and arch your torso. Then exhale and bring your hands back to your heart. Repeat the sequence 6 more times.
