Exercise guide

Spiderman Front Plank

  • Intermediate
  • Compound
  • Timed hold
  • Shoulders
  • Waist

This dynamic plank variation intensifies core engagement by targeting the obliques and hip flexors while demanding significant shoulder and glute stability. It effectively builds anti-rotational strength and improves hip mobility through a functional, multi-joint movement.

  • Erector spinae
  • Serratus anterior

Equipment

  • Body weight

Setup

  1. Begin in a standard forearm plank position with your elbows directly underneath your shoulders.
  2. Engage your core, squeeze your glutes, and tuck your pelvis slightly to create a straight line from head to heels.
  3. Position your feet hip-width apart to provide a stable base for the unilateral movement.

How to do it

  1. Exhale as you lift your right foot and drive your right knee toward the outside of your right elbow in a smooth, controlled arc.
  2. Inhale as you slowly return your right foot to the starting position, ensuring your hips do not sag or rotate.
  3. Repeat the movement on the left side, alternating legs while maintaining a steady 2-second tempo for each repetition.
  4. Keep your gaze fixed on the floor between your forearms to maintain a neutral cervical spine throughout the set.

Form checklist

  • Keep hips level and parallel to the floor; avoid letting them tilt toward the moving leg.
  • Maintain a strong 'hollow body' position to prevent the lower back from arching.
  • Ensure elbows remain stacked directly under the shoulders to maximize joint stability.
  • Keep the moving foot hovering just above the ground rather than dragging it.

Pro tips

  • Focus on the 'crunch' sensation in your side; imagine trying to touch your knee to your tricep to maximize oblique recruitment.
  • Actively push your forearms into the floor to engage the serratus anterior and stabilize the shoulder girdle.

Make it harder

  • Perform the exercise from a high plank (push-up) position to increase the range of motion and shoulder stability requirements.
  • Add a 2-second isometric hold at the peak of the contraction when the knee is closest to the elbow.
