The Half-Kneeling Cable Oblique Crunch, and it's excellent for developing rotational core strength, lateral trunk stability, and the ability to transfer force during the golf swing.

For golfers, focus on quality over weight. The goal is to feel the obliques doing the work while keeping your hips and shoulders controlled, rather than simply moving the heaviest band possible.

• Attach a resistance band to a high anchor point.
• Assume a half-kneeling position with the knee closest to the anchor on the floor and the opposite foot planted firmly in front.
• Hold the band with the hand farthest from the anchor and bring your elbow down so your upper arm is roughly in line with your shoulder.

1. Brace your core and keep your chest tall before beginning the movement.
2. Without rotating your torso, pull your rib cage toward your front hip, performing a controlled side crunch.
3. Pause briefly at the bottom while squeezing your oblique muscles.
4. Slowly return to the starting position, resisting the pull of the band the entire way.
5. Complete all repetitions on one side before switching sides.

• Brace your core before you move. Think about tightening your abs as if someone is about to poke you in the stomach.
• Keep your chest facing forward. Avoid rotating your shoulders. This is a side-bending movement, not a twisting exercise.
• Lead with your ribs, not your elbow. Imagine you're trying to bring your lower ribs toward your front hip. The elbow simply follows the movement.
• Keep your hips level and still. Your pelvis should stay square throughout the exercise. If your hips start shifting side to side, the resistance is probably too heavy.
• Maintain a tall posture. Stay long through your spine before initiating each repetition. Don't start already leaning toward the band.
• Squeeze at the bottom. Hold the contracted position for 1–2 seconds to maximize activation of the obliques.
• Control the return. Resist the band as you slowly return to the starting position. The eccentric (lowering) phase is just as important as the crunch.

• Pulling with the arm instead of using the core.
• Twisting the shoulders instead of side bending.
• Leaning the whole body rather than isolating the torso.
• Losing a tall posture during the movement.
• Allowing the hips to shift sideways.
• Rushing the lowering phase.
• Holding your breath throughout the exercise.
