Australian grip guy Isaac Pitt has proven his excellent all-around grip strength by certifying on the IronMind Crushed-To-Dust® (CTD) Challenge.

Conceived as a quick, fun, universal standard for testing/demonstrating excellent all-around grip strength, the Crushed-To-Dust Challenge tests both pinch (IronMind Hub) and crushing grip (Captains of Crush® gripper and Rolling Thunder®):

Lifting 20 kg/45 lb. on the IronMind Hub
Lifting 90 kg/200 lb. on the Rolling Thunder®
Closing the No. 2 Captains of Crush® gripper

Grip strength luminary Clay Edgin was the first to qualify (in 2012) and since then the CTD challenge has spread worldwide with certifications in 16 counties to date, with USA, Russia, Ukraine, Canada, Germany and Finland dominating the roll.

Pitt told IronMind, “Other grip feats I've done include lifting the 78-kg Holle Inch dumbbell, the 83-kg HK dumbbell and the Fatman blob. I'm hoping to get 100 kg+ on the IronMind Little Big Horn in the future. I organise the Australian Grip Sport Championship and this year we will be including the IronMind Silver Bullet Hold for time."
