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.
