Target your training: focus on one or two fingers at a time--even your thumb:

• pinch or crush--your choice--one or two fingers at a time
• precision manufacturing for world-class performance, feel, and appearance
• perfect--and portable--way to train your thumb
• proprietary IronMind GR8 springs in 7 strengths: precise, durable, good-looking
• ergonomic handles for reduced pressure on soft tissue of hands
• CoC compatible: works hand-in-glove with Captains of Crush Grippers

Can't quite put away a CoC No. 2? Hit your pinkie and ring fingers with an IMTUG3 or IMTUG4 and see what happens.

Want to certify on the CoC No. 3 or beyond? Meet IMTUG5, IMTUG6, and IMTUG7.

Want a portable way to train your pinch grip? IMTUG1, IMTUG2, or IMTUG3 should be in your pocket.

Choose the IMTUG based on the relative strength of your fingers:

Thumb - weakest - use an easier IMTUG
Ring and pinkie fingers - moderate - use a medium IMTUG
Index and middle fingers - strongest - use a tougher IMTUG
Which IMTUGs should you choose? Use the following guide to select the right level of IMTUGs based on which Captains of Crush Gripper you are training with:

Guide or Sport - IMTUG1, IMTUG2
Trainer or No. 1 - IMTUG2, IMTUG3, IMTUG4
No. 1 or No. 2 - IMTUG3, IMTUG4, IMTUG5
No. 2 or No. 3 - IMTUG4, IMTUG5, IMTUG6
No. 3 or No. 4 - IMTUG5, IMTUG6, IMTUG 7
