Spider Mountain Climber

Body WeightIntermediate

Begin in a high plank position with your hands directly under your shoulders. Keep your body in a straight line from head to heels.

  1. Bring your right knee towards your right elbow, engaging your core.
  2. Quickly switch legs, bringing your left knee towards your left elbow.
  3. Continue alternating legs in a controlled manner, maintaining your plank position.

Focus on keeping your hips low and your movements smooth.

How to perform the Spider Mountain Climber

  1. Set up. Set up in a stable, balanced starting position appropriate for the Spider Mountain Climber 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 primary working muscles.
  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 working muscles 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.
