RE Renaissance Balance Ball 55cm, Suitable for Heights 150-170cm, Weight Capacity 300kg (Includes Fixing Ring and Pump), Core Exercise, Can Be Used As

[Sitting becomes exercise] The elasticity and inherent instability of a balance ball help strengthen your core muscles. Using it instead of a chair transforms it into a gentle exercise.

[Safe with a fixing ring] Renaissance balance balls come with a fixing ring, making it easy to sit while maintaining balance. This makes them safe for those unfamiliar with sitting on an unstable ball, and for elderly people whose core and leg strength have weakened, reducing their balance.

Burst-resistant type

[Hand pump included] A hand pump is included, so you can inflate it and use it right away. *Due to the nature of the durable material, if it does not inflate to the indicated size in one go, please wait a while and patiently inflate it in several stages.

[Thick and durable material] Excellent stability when sitting. With just the right amount of elasticity and rebound, it is suitable for training, and movements such as rocking and rotating the pelvis back and forth and side to side while sitting on the ball are smooth and comfortable!
