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.

Setup
- Begin in a high plank position with your hands directly under your shoulders and feet hip-width apart.
- Walk your hands and feet out slightly wider than a standard plank to form a 'star' shape with your body.
- 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
- Exhale as you shift your weight onto your left hand and right foot, lifting your right hand and left leg simultaneously.
- 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.
- Inhale as you slowly return your hand and foot to the wide starting position with total control.
- 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.
