I’m a personal trainer — and I think the balance trainer is the most underrated piece of gym equipment you’re not using to build strength, stability and balance in your muscles.
Also known as the Bosu ball, the kit looks basic, but it’s brilliant for assisting with all functional training. So whether you enjoy cardio, strength programs, agility or sports — adding one to your arsenal could strengthen your entire body and improve core stability, proprioception, coordination and balance.
