Setup

  1. Lie face down on a flat surface with your legs straight and arms extended fully overhead.
  2. Position your forehead on the floor or keep your gaze directed straight down to maintain a neutral cervical spine.
  3. Engage your core by pulling your belly button slightly away from the floor to stabilize your pelvis.

How to do it

  1. Exhale as you simultaneously lift your right arm and left leg a few inches off the ground, keeping both limbs straight.
  2. Hold the top position for one second, focusing on squeezing the glute of the lifted leg and the muscles of the lower back.
  3. Inhale as you slowly lower both limbs back to the starting position with total control.
  4. Repeat the movement using your left arm and right leg, alternating sides for the remainder of the set.

Form checklist

  • Keep your neck neutral by looking at the floor to avoid cervical strain.
  • Focus on reaching your arm and leg toward opposite walls rather than just lifting them high.
  • Keep your hips pinned to the floor; do not allow your pelvis to rotate as you lift.
  • Ensure the movement is driven by the glutes and erectors, not by swinging the limbs with momentum.

Pro tips

  • To maximize glute recruitment, ensure your thigh clears the floor while keeping the knee locked straight.
  • Maintain a slight 'hollow body' sensation in the abdomen to protect the lumbar spine from excessive arching.

Make it harder

  • Increase the isometric hold at the top of each rep to 3-5 seconds to build endurance.
  • Hover all four limbs slightly off the ground between reps so the muscles never fully relax.
