Heavy-duty vinyl exercise balls for back support

An essential tool for stretching and gentle muscle strengthening, exercise balls allow you to engage your core and target deep stabilizing muscles. The thick vinyl construction of our exercise balls provides excellent lumbar support during floor exercises, helping to relieve back tension. Their textured, non-slip surface prevents sliding, ensuring total stability on all types of flooring.

Designed for long-lasting and safe home workouts, our balls are built with heavy-duty materials. To make life easier, Decathlon includes a spare stopper right in the box. Be sure to pick up our compatible pump, sold separately, to easily inflate your ball to your preferred firmness.

How to choose the right size exercise ball?

To train with proper posture and prevent improper alignment, the diameter of the ball should be selected based on your height and weight. A larger model is ideal for taller individuals to maintain the body's natural alignment. Selecting the right size ensures a proper range of motion and maximum comfort during every exercise.

Once your exercise ball is inflated, perform a simple test: sit on it with your feet flat on the floor. Your knees should be at the same height as your hips, forming a 90-degree angle. If your thighs slope downward or your knees rise above your hips, slightly adjust the air pressure or choose the next size up.
