Torso Resistance

The Skill: Core Strength

Strong muscles in your torso and hips generate force and support the movements of your arms and legs, whether you're swinging a golf club or jumping waves.

The Move: Torso Resistance

Attach a resistance band to the knob of a closed door. Hold the band in front of you in both hands, keeping your arms straight. Turn so you're standing with your right side facing the door. Take a few steps to the left until you feel resistance; hold that position for 30 seconds. Engage your core to keep your torso from turning toward the door. Rest for 10 seconds. Do four reps, then turn around and repeat on the other side.

Body Bonus

This exercise also improves your posture.

Wood Chop with Resistance Band

Stand to the right of a resistance band (secured a few feet above your head). With your feet hip-width apart, rotate your torso slightly to the left and grab the handles with both hands so that your arms are straight and above your left shoulder. Keeping your arms straight and back flat, pull the handles across your body to the outside of your right knee. Pause, then slowly return to start. That's one rep. Do 12 to 15 total, then switch sides and repeat.
