PhysKcal Gym Ball 55-85cm Exercise Swiss Ball for Fitness Yoga Pilates Pregnancy, Anti Burst Ball Chair for Balance, Stability, Quick Pump Included

•- -: PhysKcal Gym Ball 55cm Lavender supports up to 300kg/660lbs dynamic load (2000lbs for static load) since it was created with sufficient high-grade PVC material, allowing it deflates slowly instead of bursting. The frosted finish enhanced with anti-slip rings surrouding the ball provide more grip during exercise to aid balance and avoid rolling.

•: A gym ball, or also known as fitness ball, physio ball, yoga ball or balance ball is normally made of PVC. We upgraded the grade of PVC of our gym ball to a 16p-free level. It is free from phthalates, latex, BPA and other leading harmful chemicals, thus offering a safe and gentle support for exercise, seat and pregnancy.

•: You may ever heard of Lebron James’ favoritism about training with swiss balls. He always ends or starts workouts by balancing on a swiss ball for up to an hour. He even takes this physio ball to another notch by holding weights to further intensify the finisher workouts. To get strong and stable cores is difficult, but hard work pays off!

•: An exercise ball is an unstable unit—when you sit on this ball or use it for a workout, the muscles that stabilize your spine are activated in order to keep you from losing balance. This activation of your spinal muscles can help strengthen your torso function in your back. To choose an appropriate size of gym ball for different purposes of use, see our size guide in picture 6.

•: 1x Hand Pump, 2x Plugs, 1x Plug Remover, 1x Graphic Inrstruction and 1x Measuring Tape are included in the package. Follow our instructions to properly inflate and take care of your gym ball.
