Mountain Climber

Alternate driving knees toward your chest from a high plank, using fast, repeated drives to elevate heart rate while challenging the core, shoulders, and hips.

How to do the Mountain Climber#

  1. Set up in a high plank with hands under your shoulders, legs straight, and body forming a straight line from head to heels.
  2. Brace your core and pull one knee rapidly toward your chest while keeping your hips low and shoulders stable.
  3. Extend that leg back as you immediately drive the opposite knee forward, switching legs in a smooth, quick rhythm.
  4. Keep your hands planted and maintain a neutral spine; move with controlled speed rather than uncontrolled bouncing.
  5. Breathe steadily throughout and focus on steady shoulder position and core tension as you alternate legs.

Frequently asked questions#

What muscles does the Mountain Climber work?

The Mountain Climber primarily works the abs, hip flexors. The quads, front delts, chest, triceps assist as secondary muscles — they stabilise the movement and take over when the main target fatigues. If you feel it mostly in the quads, front delts, chest, triceps, lighten the load and slow the lowering phase.

What equipment do I need for the Mountain Climber?

None. The Mountain Climber is a bodyweight exercise, so all you need is enough space to move through the full range of motion.

Is the Mountain Climber suitable for beginners?

Yes. The Mountain Climber is rated beginner: the technique is quick to pick up and forgiving when a rep goes slightly off. Start light and add weight once the form repeats itself without you thinking about it.

What are good alternatives to the Mountain Climber?

Ab Coaster, Ab Wheel, Air Bike all train the same primary muscles as the Mountain Climber. Pick whichever one matches the equipment in front of you.
