Product Review

Owning the Iron Grip Adjustable Gripper 90 EXT is like owning six separate metal hand grippers. This single gripper provides resistance from beginning to professional levels.

Stage 1. 55lb (25kg)
Stage 2. 84lb (38kg)
Stage 3. 112lb (51kg)
Stage 4. 141lb (64kg)
Stage 5. 170lb (77kg)
Stage 6. 198lb (90kg)

Extending the handles with the provided add-on parts provides easier handling for people with larger-sized hands. The extension also increases the resistance depending on your grip position which allows you to set various training strengths.

AND A SPECIAL BENEFIT FOR OWNERS of the GD Iron Grip EXT 80 or 90. The manufacturer will award special editions of the EXT 90 to 100 people who can close this gripper at 80 or 90 kg. The gripper will contain custom laser markings with the person's name, closing date, serial number, and the title "King of Crush." Individuals will need to record a Youtube video clearly showing the closing of the gripper. They then must email the link to manufacturer. Please see the GDGrip site for more details.
