The Up Hook is an explosive rotational strike that generates power from the ground up, utilizing the core and hips to drive the fist in an upward arc. This movement builds functional strength in the obliques and shoulders while improving total-body coordination and cardiovascular endurance.

Setup

  1. Stand in a boxing stance with your feet shoulder-width apart, knees slightly bent, and your lead foot forward.
  2. Hold your gloves at cheek level in a high guard position with your elbows tucked in toward your ribs.
  3. Position yourself at a distance where you can comfortably reach the bag with a bent arm.
  4. Distribute your weight evenly on the balls of your feet to allow for quick rotation.

How to do it

  1. Slightly dip your shoulder on the striking side and shift your weight toward that leg to load the hips.
  2. Rotate your hips and torso explosively while driving your glove upward in a 'J' shaped arc toward the bag, exhaling sharply on impact.
  3. Maintain a 90-degree bend in your elbow and keep your palm facing toward your chest as you strike.
  4. Snap the glove back to your face immediately after impact and reset your stance before alternating sides.

Form checklist

  • Pivot on the ball of the foot on the striking side to ensure full hip rotation.
  • Keep the non-striking hand glued to your face to maintain a defensive guard.
  • Avoid 'winding up' by dropping your hand; the power should come from the legs and core, not a long arm swing.
  • Keep your core braced throughout the entire rotation to protect the lower back.

Pro tips

  • Focus on 'digging' the punch into the bag rather than just hitting the surface to maximize pectoral and oblique engagement.
  • Ensure your elbow follows the path of your fist to provide structural support and prevent wrist strain.

Make it harder

  • Incorporate a squat or a 'slip' (lateral head movement) between each alternating hook to increase lower body and core demand.
  • Perform high-intensity intervals by throwing alternating hooks at maximum speed for 30-second bursts.
