Exercise guide

Chop Knee Raise

  • Intermediate
  • Compound
  • Rep-based
  • Back
  • Shoulders
  • Waist

The Chop Knee Raise is a dynamic standing core exercise that integrates rotational power with hip flexion to target the obliques, rectus abdominis, and hip flexors. It improves functional stability and coordination by mimicking a diagonal chopping motion against the resistance of your own body weight.

Secondary

  • Deltoids
  • Erector spinae

Equipment

  • Body weight

Setup

  1. Stand with your feet shoulder-width apart and a slight bend in your knees.
  2. Clasp your hands together and reach them diagonally overhead to your right side, fully extending your arms.
  3. Shift your weight slightly onto your right leg, preparing to drive the left knee.

How to do it

  1. Exhale sharply and pull your hands down diagonally across your body toward your left hip.
  2. Simultaneously drive your left knee up toward your chest, meeting your hands at waist level in a 'crunching' motion.
  3. Inhale as you return your leg to the floor and reach your arms back to the starting overhead position with control.
  4. Perform the desired repetitions on one side, then switch to the other side, or alternate sides as programmed.

Form checklist

  • Rotate through your torso and shoulders, not just your arms.
  • Keep your standing leg slightly bent for better balance and stability.
  • Maintain a tall spine and avoid excessive rounding of the lower back during the chop.
  • Engage your core before starting the movement to protect the spine.

Pro tips

  • Focus on the 'mind-muscle connection' by imagining you are pulling a heavy cable down to create internal tension in the obliques.
  • Squeeze your abs hard at the point where your hands and knee meet to maximize the peak contraction.

Make it harder

  • Increase the speed of the movement to add a cardiovascular and explosive power element.
  • Hold a light medicine ball or a small dumbbell to increase the rotational load on the core.
