Add an element of instability to your workout and strengthen your core muscles, proprioception (balance & coordination) and posture. The unstable surface forces your body to constantly adjust and stabilise through the key joints in ankle, knee and hip. This optimally activates the deep abdominal muscles, hip muscles, glutes and the muscles of the lower and upper back.
Our Instaball is designed for versatility and durability: both sides can be used for various exercises and different levels of instability. The grooves provide extra grip at multiple points of contact with the body, allowing you to train safely and effectively.
