Mountain Climber

AbsBodyweight

Mountain Climbers are a dynamic conditioning move that builds core strength and boosts endurance. They mimic a high-tempo climb to fire up your abs and work your entire body.

How to do it

1Set up in a high plank position with your hands directly under your shoulders and your body forming a straight line from head to heels.

2Keep your back flat, don't let your hips sag or pike up, and fix your gaze on the floor just ahead of your hands.

3Drive one knee toward your chest, then quickly switch legs, running in place in a plank position.

4Aim to pull your knee toward your elbow or chest while keeping your torso completely still.

5Return your foot to the start position and immediately pull the other knee in. Keep moving at a controlled pace.

Common mistakes

Letting your hips sag or piking them up—this takes the tension off your core and stresses your lower back.

Bouncing or swaying your torso from side to side—keep your upper body locked down and move only your legs.

Rushing the tempo at the expense of form—slow down, stay in control, and feel your core working.

Placing your hands too far forward—keep them right under your shoulders to protect your wrists.

Breathing

Breathe rhythmically and smoothly: exhale as you drive your knee to your chest, and inhale as you extend your leg back. Never hold your breath.

Make it harder or easier

To make it easier: slow down the pace, tap your toes to the floor on each rep, or elevate your hands on a bench or sturdy chair.

To make it harder: pick up the speed while maintaining core stability, or drive your knees diagonally toward opposite elbows for a twist.

For advanced lifters: wear ankle weights or perform the move with your hands on an unstable surface like a Bosu ball.

This is general guidance, not a medical opinion. Listen to your body: if it hurts, stop. If you have an injury or a chronic condition, talk to a doctor first.
