How to perform

Engage your core and press your lower back into the mat. Lift your torso and legs together, bending your knees and reaching your hands towards your shins to form a V shape. Squeeze your abs at the peak, then slowly lower with control, extending fully without touching the floor.

Tips

Press your lower back firmly against the mat throughout the exercise to protect your spine and maintain a stable base. Lift your torso and legs simultaneously, focusing on using your abdominal muscles to power the movement rather than momentum. Reach your hands towards your shins, keeping your knees bent to avoid overextending your hamstrings and maintain a comfortable angle. Keep your neck neutral by gazing slightly forward, preventing strain and ensuring proper spinal alignment. Lower your torso and legs with deliberate control, resisting the urge to drop quickly to maximize muscle engagement and prevent injury.
