How to do a plank

A plank is not an endurance contest — it is a maximum-tension drill, and 30 honest seconds beats three minutes of sagging.

Muscles worked: Rectus abdominis, Transverse abdominis, Obliques, Glutes

How to do it

  1. Set the elbows under the shoulders and the forearms parallel, feet about hip width.
  2. Tuck the tailbone slightly so the low back flattens instead of arching.
  3. Squeeze the glutes hard and pull the belly button toward the spine.
  4. Pull the elbows toward your toes without moving them — the whole body should shake within a few seconds.
  5. Breathe shallow and steady, and end the set the moment the hips drop.

Mistakes to avoid

  • Holding for time with sagging hips instead of stopping at the first break in form.
  • Piking the hips up to make it easier.
  • Holding the breath, which is what makes long planks feel impossible.
