Wall Plank

  • Beginner
  • Compound
  • Timed hold
  • Shoulders
  • Waist

The wall plank is a beginner-friendly core stability exercise that builds isometric strength in the abdominals and shoulders while reducing lower back strain. It effectively teaches core bracing and shoulder stability by utilizing a vertical surface to modify the gravity-based load.

Muscles worked

  • Serratus anterior
  • Trapezius

Equipment

  • Body weight

Setup

  1. Stand facing a wall with your feet hip-width apart.
  2. Place your forearms against the wall at shoulder height, keeping them parallel to each other.
  3. Step your feet back 1-2 feet until your body is at a slight incline, resting your weight on the balls of your feet.

How to do it

  1. Engage your core and squeeze your glutes to create a straight line from your head to your heels.
  2. Press your forearms firmly into the wall to protract your shoulder blades and engage the serratus anterior.
  3. Hold this position while maintaining a steady breathing pattern, inhaling through the nose and exhaling forcefully through the mouth.
  4. Maintain a controlled tempo by holding the isometric contraction for the desired duration without letting the hips sag.

Form checklist

  • Keep your neck neutral by looking at the wall directly between your forearms.
  • Ensure your elbows are aligned directly under your shoulders.
  • Avoid arching your lower back; keep your pelvis tucked slightly under.
  • Keep your shoulder blades spread wide rather than letting them collapse together.

Pro tips

  • Create 'internal tension' by trying to pull your elbows down toward your toes without actually moving them.
  • Focus on pushing the wall away from you to maximize engagement of the deltoids and upper back.
  • Exhale deeply to help 'knit' your ribs toward your hips, increasing deep abdominal activation.

Make it harder

  • Walk your feet further away from the wall to increase the incline and the demand on your core.
  • Lift one leg slightly off the floor to create a three-point plank, challenging your obliques and rotational stability.
