Setup

  1. Lie flat on your back with your knees bent and feet planted firmly on the floor, hip-width apart.
  2. Hold a single kettlebell with both hands by the horns (the sides of the handle) resting against your upper chest.
  3. Tuck your chin slightly and engage your core to eliminate the arch in your lower back.

How to do it

  1. Exhale and perform a controlled sit-up, peeling your spine off the floor while keeping the kettlebell tucked close to your chest.
  2. Once your torso is vertical, immediately press the kettlebell straight overhead until your elbows are fully locked out.
  3. Inhale as you lower the kettlebell back to your chest and slowly roll your spine back down to the floor one vertebra at a time.
  4. Maintain a steady tempo, avoiding the use of momentum to 'swing' yourself upward.

Form checklist

  • Keep your feet glued to the floor; if they lift, tuck them under a heavy object or widen your stance.
  • Ensure your biceps are aligned with your ears at the top of the press.
  • Maintain a tall, neutral spine at the top of the movement without arching your lower back.
  • Control the descent to the floor to maximize time under tension for the abdominals.

Pro tips

  • Focus on the 'segmental' roll of the spine during the descent to maximize eccentric abdominal engagement.
  • At the peak of the press, 'punch' the kettlebell toward the ceiling to fully activate the serratus anterior and upper traps.

Make it harder

  • Straighten your legs out completely on the floor to remove hip flexor assistance and increase the core demand.
  • Perform the movement holding the kettlebell in a single-arm rack position to add a significant anti-rotational challenge.
