Plank arm lifts

Begin in a front plank position with your body in a straight line from head to heels.

  1. Engage your core and maintain a stable position.
  2. Slowly lift one arm straight in front of you, keeping your hips level.
  3. Hold for a moment, then lower your arm back to the starting position.
  4. Repeat with the opposite arm.

How to perform the Plank arm lifts

  1. Set up. Set up in a stable, balanced starting position appropriate for the Plank arm lifts using your body weight.
  2. Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your abdominals.
  3. Reset. Reverse the movement under control and reset between repetitions, keeping your form crisp on every rep.

Coaching cues

  • Move with intent — every rep should feel deliberate, not rushed.
  • Drive force through your abdominals rather than momentum.
  • Keep your breathing steady: exhale on the hard part, inhale on the reset.

Common mistakes

  • Using too much weight and losing positional control.
  • Cutting the range of motion short and missing the target muscle.
  • Letting your spine round or hyperextend instead of staying neutral.
