Secondary
Delts, Glutes

How to do it

  1. Lie face down on the floor with your forearms resting flat on the ground, elbows positioned directly underneath your shoulder joints.
  2. Extend your legs straight back behind you and rise up onto the balls of your feet.
  3. Squeeze your glutes tightly and brace your abdominal wall as if preparing to take a punch.
  4. Establish a perfectly straight, rigid line from the back of your head down through your hips to your heels.
  5. Keep your gaze fixed on the floor slightly ahead of your hands to maintain a neutral neck alignment.
  6. Breathe steadily and hold this rigid position for the designated duration without letting your hips sag or pike upward.

Coaching cues

  • Body forms a rigid plank from head to heels
  • Squeeze the glutes and brace the core
  • Keep hips level, no sagging

Common mistakes

  • Sagging the lower back toward the floor due to fatigue or weak core engagement
  • Piking the hips high up into the air, reducing abdominal load
  • Holding your breath during the hold
