New Balance Ball 55cm Exercise Yoga Fitness Ball Core Training Please read the self-introduction. ○○ Balance Ball 55cm ○○ Air pump not included. The color is as shown in the first photo. Logos may vary. This balance ball can be widely used for exercise, dieting, core training, and as an office chair. Just sitting on the unstable ball strengthens your core, improves posture, and is said to be effective for stiff shoulders and lower back pain. Why not train slowly and comfortably at home? ☺︎ ・Anti-burst specification that prevents bursting even if a hole is made. If a hole is made in the ball, it will deflate gradually instead of bursting like a balloon, which is dangerous. ・As for the air pump, you can use one sold at 100-yen shops, so we recommend that. Yoga mats and foam rollers can be discounted as a set, so take this opportunity! ↓ #archiYogaMat #archiFoamRoller #archiBoxing #balanceball #fitnessball #yoga #core #coretraining #senseofbalance
