  • Obliques

Equipment

  • Body weight

Setup

  1. Start on all fours in a quadruped position with your hands directly under your shoulders and knees under your hips.
  2. Engage your core to create a flat, neutral spine from head to tailbone.
  3. Distribute your weight evenly between your hands and the stationary knee.

How to do it

  1. Keeping your working knee bent at a 90-degree angle, exhale and lift your heel toward the ceiling by extending the hip.
  2. Squeeze your glute at the top of the movement, ensuring your lower back does not arch or dip.
  3. Inhale as you slowly lower the knee back toward the floor with a 2-second eccentric tempo.
  4. Complete the desired repetitions on one leg before switching to the other side.

Form checklist

  • Keep your hips square to the floor; do not let the pelvis rotate or tilt.
  • Maintain a braced core to prevent the lower back from rounding or arching.
  • Keep your neck neutral by looking at the floor slightly ahead of your hands.
  • Drive the movement through the heel rather than the toes.

Pro tips

  • Pause for one second at the peak of the contraction to maximize gluteal fiber recruitment.
  • Imagine you are trying to leave a footprint on the ceiling to ensure the force is coming from hip extension rather than leg swinging.

Make it harder

  • Perform the movement with a straight leg to increase the lever arm and hamstring tension.
  • Add a 3-second isometric hold at the top of every repetition.
