Exercise guide

Single Arm Overhead Dumbbell Squat

  • Advanced
  • Compound
  • Rep-based
  • Lower legs
  • Upper legs

This advanced compound movement builds exceptional total-body stability and core strength while challenging shoulder mobility and lower-body power. The unilateral overhead load forces the obliques and spinal stabilizers to work intensely to maintain an upright posture against the offset weight.

Setup

  1. Stand with feet slightly wider than shoulder-width apart and toes turned out 15-30 degrees.
  2. Press the dumbbell overhead with one arm, locking the elbow completely and stabilizing the shoulder blade.
  3. Extend the opposite arm out to the side at shoulder height to act as a counterbalance.
  4. Brace your core tightly and set your gaze on a point straight ahead or slightly upward toward the weight.

How to do it

  1. Inhale as you lower into a squat by pushing your hips back and bending your knees, keeping the dumbbell vertically aligned over your shoulder and mid-foot.
  2. Descend until your thighs are at least parallel to the floor, ensuring your torso remains as upright as possible to prevent the weight from drifting.
  3. Exhale and drive through your heels to return to a standing position, maintaining a locked-out arm and a rigid core throughout the ascent.
  4. Complete all repetitions on one side before switching the dumbbell to the other arm.

Form checklist

  • Keep the overhead arm perfectly vertical; do not let the weight drift forward or out to the side.
  • Ensure the knees track in line with the toes and do not cave inward during the descent or ascent.
  • Maintain a neutral spine and avoid excessive arching in the lower back to compensate for shoulder tightness.
  • Keep the weight distributed evenly across both feet despite the unilateral load overhead.

Pro tips

  • Actively 'push' the dumbbell toward the ceiling throughout the entire movement to engage the serratus anterior and maximize shoulder stability.
  • Focus on squeezing the glute of the opposite leg as you drive upward to help stabilize the pelvis against the unilateral load.
  • If balance is an issue, slow the tempo to a 3-second eccentric (lowering) phase to better identify where your center of gravity is shifting.

Make it harder

  • Add a 3-second pause at the bottom of the squat to maximize the stability demand on the core and shoulder stabilizers.
  • Perform the movement with a kettlebell in the overhead position; the offset center of mass increases the rotational challenge on the shoulder.
