Equipment

  • Dumbbell

Setup

  1. Stand with feet shoulder-width apart, holding a pair of dumbbells at shoulder height with a neutral grip (palms facing each other).
  2. Position your elbows slightly in front of your ribs and engage your core to stabilize your spine.
  3. Distribute your weight evenly across your feet with a slight outward toe flare.

How to do it

  1. Inhale as you lower your hips into a squat until your thighs are at least parallel to the floor, keeping your chest upright.
  2. Exhale and drive explosively through your heels to stand up, using the upward momentum to press one dumbbell vertically overhead.
  3. Lower the dumbbell back to the starting shoulder position in a controlled manner as you begin the next squat.
  4. Repeat the movement, pressing the opposite arm overhead on the next ascent in an alternating fashion.

Form checklist

  • Keep your heels firmly planted on the ground throughout the squat phase.
  • Ensure the overhead press is a fluid continuation of the leg drive, not two separate movements.
  • Maintain a neutral spine and avoid leaning to one side as you press the single dumbbell.
  • Keep your bicep close to your ear at the top of the press for a stable lockout.

Pro tips

  • Think of the squat as the engine that drives the weight up; the arm should only finish the movement that the legs started.
  • Squeeze your glutes hard at the top of the movement to provide a stable base for the unilateral press.

Make it harder

  • Increase the speed of the repetitions to emphasize cardiovascular demand and power output.
  • Add a three-second eccentric lowering phase to the squat to increase time under tension for the lower body.
