Kneeling Plank

  • Lower arms
  • Shoulders

The kneeling plank is a foundational core stability exercise that builds isometric strength in the abdominals and glutes with reduced leverage, making it ideal for beginners. It focuses on maintaining a neutral spine and pelvic control to prepare the body for more advanced plank variations.

Equipment

  • Body weight

Setup

  1. Start on all fours on a mat with your forearms on the floor.
  2. Position your elbows directly underneath your shoulders.
  3. Walk your knees back until your body forms a straight line from your head to your knees.
  4. Keep your feet relaxed or toes tucked for stability.

How to do it

  1. Engage your core by pulling your navel toward your spine and squeezing your glutes firmly.
  2. Maintain a neutral neck by looking at the floor between your forearms.
  3. Breathe deeply and steadily through your nose, avoiding the tendency to hold your breath.
  4. Hold the position for the target duration, keeping your torso rigid and hips level.

Form checklist

  • Don't let your lower back arch or sag toward the floor.
  • Keep your shoulder blades pushed apart rather than letting them collapse together.
  • Ensure your hips stay in a straight line with your shoulders and knees.
  • Keep your weight distributed evenly across your forearms.

Pro tips

  • Actively drive your elbows into the floor to engage the serratus anterior and stabilize the shoulders.
  • Imagine pulling your elbows toward your knees (without actually moving them) to create intense 'bracing' tension throughout the entire abdominal wall.

Make it harder

  • Lift one knee slightly off the floor to challenge your rotational stability.
  • Slowly rock your body forward and backward an inch to increase the demand on the core and shoulders.
