Get into plank position by supporting your body weight on your hands and toes.


Step 2

Hands should be placed directly under your shoulders.

Step 3

Keep your abdominals contracted and your back straight, eyes ahead of you.

Step 4

Hold this position for as long as you can, building up to 1 minute.
