Mountain climber: how to do it

In short

A high plank where you step one knee toward your chest, then the other, like a slow march on your hands. Works: core, whole body and shoulders.

In a high plank on a mat, a man draws one knee in toward his chest.

How to do it

  1. Come onto a mat or folded towel on a non-slip floor, on your hands and toes, hands under your shoulders.
  2. Make one straight line from head to heels and draw your lower belly in a little.
  3. Step one foot forward and bring that knee toward your chest.
  4. Step it back and bring the other knee in.
  5. Keep going slowly for about 20 seconds, then lower your knees and rest.

As you go

  • Keep your hips low and level, no bouncing up.
  • Breathe steadily. Never hold your breath.
  • Press the floor away so your shoulders stay over your hands.

An easier and a harder version

Easier

Put your hands on a sturdy counter and march your knees in from there, or lower your knees for a knee plank.

Harder

Move a little faster while your hips stay level, or go for 30 seconds.

Take care
  • Wrists: if your wrists complain, make soft fists, use your forearms, or put your hands on a counter.
  • Shoulders: stop short of any pinch.
  • Back: if your lower back sags or aches, slow down or use a counter.
