The front plank is a foundational isometric core exercise that builds stability and endurance across the entire anterior chain. It effectively engages the rectus abdominis and obliques while requiring total-body tension to maintain a neutral spine.

Muscles worked

  • Erector spinae
  • Serratus anterior
  • Trapezius

Equipment

  • Body weight

Setup

  1. Lie face down on the floor with your forearms flat and elbows positioned directly under your shoulders.
  2. Place your feet hip-width apart with your toes tucked under.
  3. Engage your core and lift your hips until your body forms a straight line from head to heels.

How to do it

  1. Maintain a neutral spine by looking at the floor slightly in front of your hands.
  2. Breathe deeply and steadily through your nose, maintaining constant intra-abdominal pressure.
  3. Hold the position for the prescribed duration, focusing on total-body tension and avoiding any movement.

Form checklist

  • Keep your hips level with your shoulders; do not let them sag or pike upward.
  • Squeeze your glutes and quadriceps firmly to stabilize the lower body.
  • Push through your forearms to prevent your shoulder blades from collapsing together.
  • Maintain a neutral neck by keeping your gaze on the floor rather than looking forward.

Pro tips

  • Actively pull your elbows toward your toes (without actually moving them) to maximize tension in the rectus abdominis.
  • Focus on 'hollowing' your stomach by pulling your navel toward your spine to engage the deep transverse abdominis.

Make it harder

  • Lift one leg off the ground to reduce the base of support and increase rotational core demand.
  • Perform 'Plank Saws' by rocking forward and backward on your toes while maintaining a perfectly rigid torso.
