Which Pilates exercise primarily targets the inner thighs?

The Side Leg Lift is specifically designed to engage and strengthen the inner thigh muscles, known as the adductors. When performing this exercise, one leg is lifted while maintaining stability in the pelvis and core, which requires the inner thigh muscles to work actively in order to control the movement and stabilize the body. This focused engagement helps in toning and strengthening the inner thigh region effectively.

In contrast, the other exercises listed have different primary muscle targets. The Hip Bridge predominantly works the glutes and the hamstrings as it involves lifting the hips while lying on the back. The Roll Up focuses on the abdominal muscles and spinal articulation, making it a core-centric movement rather than targeting the inner thighs. Plank is an isometric exercise that primarily engages the core, shoulders, and back for stability but does not emphasize inner thigh activation. Therefore, the Side Leg Lift stands out as the exercise most closely associated with targeting the inner thighs.
