product description1. The inflatable fitness ball makes working out fun and improves balance, coordination, flexibility and strength for fitness enthusiasts, sports trainers, and even pregnant women in childbirth classes2. Explosion-proof and safe to deflate - Our fitness ball is safe with honeycomb structure, so even if you accidentally pierce the yoga ball, you won't immediately fall to the ground. This construction means that the air is released little by little, so this burst resistant and slow deflation design makes the stability ball much safer.3. Anti-Slip Material - The anti-slip wire provides more friction to the device, which means you can practice not only at home or in the gym, but also outdoors or in places like open spaces where ground conditions are harsher. Use it to increase your flexibility, boost your stretch, and maintain stability while you practice yoga or Pilates!4. Whether used as a pregnancy ball, a physiotherapy ball, a fun bouncy ball for your kids, or a professional ball for physiotherapy, it won't let you down! Enjoy a soft and comfortable stretchy texture when pressed.5. Sitting posture correction and massage: This inflatable balance ball can be effectively used as a multifunctional office ball chair. It constantly reminds you to maintain a good sitting posture as your various body parts actively make subtle adjustments to maintain balance, allowing you to sit upright automatically and increasing overall blood circulation. The soft PVC surface creates a massaging effect that relieves your fatigue while working at your desk.
