Strong hamstrings are essential for balance, power, and injury prevention. Many people overlook this muscle group, focusing more on quads or glutes.
But without well-developed hamstrings, performance in sports, weightlifting, and even daily movement suffers. One of the most effective yet underrated movements for building these muscles is the swiss ball hamstring curl.
This exercise doesn’t require heavy machines or advanced equipment. All you need is a stability ball and body control.
It challenges your hamstrings while engaging your core and glutes, making it a top-tier exercise for both athletes and fitness beginners.
What Is the Swiss Ball Hamstring Curl?
The swiss ball hamstring curl is a bodyweight exercise performed using a stability ball. You lie flat on your back, place your heels on the ball, and lift your hips while pulling the ball toward you.
This curling motion engages the hamstrings dynamically. It’s a great alternative to machines because it forces your stabilizing muscles to work harder.
Compared to the traditional leg curl machine, the hamstring curl on exercise ball improves balance and coordination while building raw strength.
Muscles Worked in the Swiss Ball Hamstring Curl
The primary muscles targeted are the hamstrings, which run along the back of the thigh. These muscles help bend the knee and extend the hip. But that’s not all.
The swiss ball hamstring curl also activates:
-
Glutes – They stabilize your hips and add power during the lift.
Calves – Assist in controlling the curl motion. -
Core muscles – Abs and lower back keep your body aligned throughout.
This means you’re not just working one muscle. You’re strengthening a chain of muscles critical for running, jumping, and lifting.
Step-by-Step Guide to Performing the Exercise
Performing the hamstring curl on exercise ball correctly ensures maximum benefits.
Follow these steps:
-
Lie on your back with your arms at your sides.
-
Place your heels on the ball with legs extended.
-
Press through your heels, lifting your hips so your body forms a straight line from shoulders to heels.
-
Slowly bend your knees, rolling the ball toward your glutes.

Keep hips elevated throughout.
-
Don’t arch your back.

Benefits of Hamstring Curls on a Stability Ball
Stability and Core Engagement
Unlike machines that isolate, the swiss ball hamstring curl engages stabilizers. Your core has to work harder, similar to when practicing yoga moves like the Warrior 3 Yoga Pose or Utthita Trikonasana - Extended Triangle Pose. This makes it a functional movement for overall strength.
Injury Prevention
Weak hamstrings are a leading cause of sports injuries. Adding this move improves balance between front and back leg muscles, reducing risks.
Athletic Performance
Stronger hamstrings support sprinting, jumping, and active sport activities. Athletes often include this move alongside drills like the Cone Reach Balance Exercise and step box exercises to enhance speed and agility.
Common Mistakes and How to Fix Them
-
Dropping hips too low – Keep them lifted to maintain tension.
-
Using momentum – Move slowly for better muscle activation.
-
Ball too far – Place it under your heels, not mid-calves.
-
Not engaging core – This reduces stability and increases injury risk.
Fix: Focus on controlled breathing and keep your body tight throughout.
Variations of the Swiss Ball Hamstring Curl
Single-Leg vs. Double-Leg Hamstring Curl
The double-leg version is beginner-friendly. Once mastered, progress to a single-leg curl. This amplifies hamstring activation and mimics real athletic movements.
Progressions for Beginners and Advanced Lifters
-
Beginners: Start with glute bridges using the ball. Then attempt partial curls.
-
Advanced lifters: Add resistance bands or elevate shoulders for extra challenge. Pair it with strength-focused moves like Top 7 Shoulder and Trap Exercises for Strength and Size or Best TRX Abdominal Oblique Exercises for full-body conditioning.
