Step by step instructions, muscle activation and variants for the Swiss Ball Leg Curl.
The exercise ball leg curl is a bodyweight hamstring exercise performed lying on your back with your feet resting on a stability ball. Rolling the ball toward your hips challenges both the hamstrings and glutes while demanding significant core stability throughout the movement.
The Swiss Ball Leg Curl is a foundational movement that builds strength and muscle through controlled, progressive overload. Train it 1 to 2 times per week with 3 to 5 working sets per session, gradually adding weight or reps as form holds up.
