Another pioneering product from LapisTM are RollyballsTM. The spherical shape of the product increases forearm and grip strength, as well as endurance. They can be used to perform various exercises, ranging from pull-ups, lockouts, chin-ups, dead hangs and, of course, regardless of the exercise performed, to improve core body strength. We recommend using a carabineer of a chain for fixation. The best training effect will be achieved in combination with the RollybarTM.
