A pike on a yoga ball begins with you assuming a plank position, placing your hands on the ground and your shins or feet resting on the ball behind you. Engage your core muscles to stabilize your body. Then, while maintaining the plank position, use your feet to roll the ball towards your hands by lifting your hips towards the ceiling and bending at the waist, aiming to bring your body into an inverted V shape. Hold this piked position briefly, feeling the stretch in your hamstrings and the engagement in your core, then carefully roll the ball back to the starting position to complete one repetition. Repeat the movement for a set number of repetitions, focusing on controlled movements and maintaining proper form throughout. This exercise targets the core, shoulders, and hip flexors while also improving flexibility and stability.
