Mountain Climber Cross Kick

Body WeightIntermediate

The Mountain Climber Cross Kick is a dynamic exercise that engages multiple muscle groups while improving coordination and cardiovascular fitness.

  1. Start in a high plank position with your hands directly under your shoulders.
  2. Drive your right knee towards your left elbow, then extend your right leg out to the side.
  3. Return to the starting position and repeat on the opposite side, driving your left knee towards your right elbow.
  4. Continue alternating sides at a steady pace.

How to perform the Mountain Climber Cross Kick

  1. Set up. Set up in a stable, balanced starting position appropriate for the Mountain Climber Cross Kick 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.
