Start with our Trainer, which is much tougher than sporting goods store grippers, and work your way up. The No. 1 will stop most guys who lift weights; the No. 2 is rarely closed the first time it is tried; the No. 3 represents a world-class crushing grip; and the No. 4 has still been closed by only one man. When you close our No. 3 or No. 4 Captains of Crush gripper under authenticated conditions, you will be certified and added to the Ironmind list.
So perhaps the "No. 1 will stop most guys who lift weights" part is a bit overstated?
