Movement overview

The Swiss Ball Leg Curl is an effective exercise targeting the hamstrings, glutes, and core muscles. It involves using a Swiss ball to perform leg curls while lying on your back, which adds an element of instability to engage stabilizing muscles.

Step-by-step cues

1. Lie flat on your back with your arms extended by your sides for stability.
2. Place your heels on top of a Swiss ball, legs straight and feet hip-width apart.
3. Lift your hips off the ground by engaging your core and glutes, forming a straight line from shoulders to heels.
4. Bend your knees and roll the ball towards your glutes by contracting your hamstrings.
5. Pause briefly at the top of the movement, ensuring your hips remain elevated.
6. Slowly extend your legs to roll the ball back to the starting position while maintaining control.
7. Repeat for the desired number of repetitions.

Technical tips

• Keep your core engaged throughout the exercise to maintain stability.
• Avoid letting your hips sag; maintain a straight line from shoulders to knees.
• Focus on controlled movements to maximize muscle engagement.
• Ensure the Swiss ball is properly inflated for optimal performance.
• Start with a smaller range of motion if you're new to this exercise and gradually increase as you gain strength.
