Improve your balance with exercise that engages arms, legs.
One of the keys to good posture is core balance. With this simple move, you can improve your muscular balance so you’ll stand taller, with your weight evenly distributed over both legs.
Start on all fours with your hands below your shoulders and your knees directly under your hips. Pull your ribcage and navel in toward the spine as you use your abdominals to “brace” the spine. Slowly shift your weight onto your right leg as you straighten and lift your left leg behind you. Reach out through your left heel, keeping your shoulders, hips and knee facing the floor. Pause for two breaths.
Keep your gaze steady and your left leg lifted as you slowly shift your weight onto your left arm. Stretch your right arm out in front of you, palm facing inward and your upper arm near the side of your head. Focus on keeping your hips and shoulders parallel to the floor. Work toward getting your extended leg and arm at the same height. Pause for three breaths. Lower your arm and leg, then repeat on the other side.
