Star Plank Toe Tap

  • Compound
  • Timed hold
  • Lower arms
  • Shoulders
  • Upper arms
  • Waist

The Star Plank Toe Tap is a dynamic core stability exercise that challenges the obliques, shoulders, and hip flexors through a cross-body reaching motion. It builds exceptional anti-rotational strength and total-body coordination by forcing the core to stabilize while moving on two points of contact.

  • Body weight

Setup

  1. Begin in a high plank position with your hands directly under your shoulders and feet hip-width apart.
  2. Walk your hands and feet out slightly wider than a standard plank to form a 'star' shape with your body.
  3. Engage your glutes and pull your belly button toward your spine to create a rigid, straight line from head to heels.

How to do it

  1. Exhale as you shift your weight onto your left hand and right foot, lifting your right hand and left leg simultaneously.
  2. Bring your right hand and left foot together under your torso, tapping your toes with your fingers while keeping your hips as level as possible.
  3. Inhale as you slowly return your hand and foot to the wide starting position with total control.
  4. Repeat the movement on the opposite side, alternating for the duration of the set at a controlled, steady tempo.

Form checklist

  • Keep your hips square to the floor; avoid rotating the pelvis as you reach.
  • Maintain a neutral neck by looking at a spot on the floor just ahead of your hands.
  • Push actively through the grounded palm to prevent your shoulder from shrugging or collapsing.
  • Do not let your lower back arch or your hips sag during the transition.

Pro tips

  • Focus on 'pushing the floor away' with your supporting arm to maximize serratus anterior and deltoid activation.
  • Pause for a split second at the peak of the tap to maximize the contraction in the obliques and lower abs.

Make it harder

  • Perform a push-up between every alternating toe tap to increase chest and tricep demand.
  • Slow down the return phase to a 3-second count to significantly increase the anti-rotational challenge.
