How To Do

Start in a standard plank with your body straight and core engaged. Extend your arms out to the sides to form a 'T' shape, keeping your palms down and arms straight while maintaining a strong, stable core. Hold this position without letting your hips sag or rise.

Step-by-Step Instructions

  1. Begin in a standard plank position with your body straight, your core engaged, and your hands directly under your shoulders.
  2. Slowly extend your arms outward to the sides, forming a 'T' shape with your upper body. Keep your palms facing down and your arms straight.
  3. Maintain a strong core and avoid letting your hips sag or rise too high. Your body should remain in a straight line from head to heels.
  4. Hold this position for the desired amount of time, ensuring your muscles remain engaged throughout.
  5. To finish, bring your arms back under your shoulders and return to the standard plank position before lowering yourself to the ground.
