ATOMIK Large Hanging Ninja Balls

The 4.5" pull-up balls are a slightly more challenging version of the 3.5" balls. Their size forces your hand open more, resulting in greater forearm engagement and faster development of the forearm muscles during your climbing grip training. These climbing balls are versatile training devices perfect for pull-ups, dead hangs, lock-offs, and obstacle course style training.
