Two-Finger Utility Gripper
The IronMind Two-Finger Utility Gripper (IMTUG) is a compact, pocket-sized grip trainer built to isolate one or two fingers – including the thumb – rather than train a full-hand close like a standard gripper. It uses the same GR8(tm) spring technology as IronMind’s Captains of Crush grippers, housed in ergonomic aluminum “hemi-end” handles designed to protect soft tissue and support the “brush technique.” It ships in seven strength levels (IMTUG1, easiest, through IMTUG7, toughest), sized to pair with a lifter’s current Captains of Crush level, and is made in the USA.
Independent coverage is thin but consistently positive on functionality: reviewers on GymRadar and in video reviews praise the ability to grip it in multiple hand positions (deep in the palm, upside down to bias the ring/pinky, or between thumb and fingertips), which makes it useful for isolating the ring and pinky fingers that usually limit a Captains of Crush close, and for rehab-style training. One long-term owner reported real carryover to grip-dependent barbell lifts, but also flagged that the springs rust faster than Captains of Crush grippers, knurling texture was inconsistent between units, and that strength gained on the IMTUG doesn’t transfer well to whole-hand Captains of Crush closing strength.

IronMind’s IMTUG is a niche but well-liked accessory for isolating individual finger and thumb strength rather than a whole-hand max-grip tool. Functionality is the standout dimension: it can be gripped deep in the palm, upside down to bias the ring and pinky, or between thumb and fingertips, and reviewers report real carryover to grip-dependent lifts like deadlifts and rack pulls. Durability is the weakest dimension — one long-term owner of six units found the knurling inconsistent between units and the springs rusting noticeably faster than IronMind’s own Captains of Crush grippers. It’s best understood as a variety and rehab tool, not a substitute for a heavy-duty gripper.
- +Functionality: can be held in multiple hand positions (deep in the palm, upside down to bias ring/pinky, between thumb and fingertips) making it useful for rehab-style training (GymRadar)
- +Functionality: isolates the ring and pinky fingers specifically, which reviewers note are usually the limiting fingers when closing a standard Captains of Crush gripper (GymRadar)
- +Functionality: real-world carryover reported to grip-dependent lifts, with one reviewer's forefinger-supinated rack pull rising from 600 to 725 lb over a training block using IMTUGs (YouTube: Buff Squirrel)
- +Value: inexpensive per unit (roughly $25-33) and pocket-sized, making it easy to add a few strength levels to a grip-training rotation (YouTube: Buff Squirrel; Rogue Fitness)
- +Versatility: doubles as a portable prehab/injury-prevention tool as well as a grip-strength accessory (IronMind manufacturer page)
- −Durability: springs and finish rust noticeably faster than IronMind's own Captains of Crush grippers over extended use (YouTube: Buff Squirrel)
- −Build quality: knurling texture was inconsistent between units within the same owner's set of six (YouTube: Buff Squirrel)
- −Functionality: strength does not carry over well to Captains of Crush whole-hand closing strength despite heavy IMTUG-specific gains (YouTube: Buff Squirrel)
- −Functionality: the toughest level (IMTUG7) tops out too easy for advanced grip athletes, who report closing it well before matching CoC #3-level strength (YouTube: Buff Squirrel)
- −Value: one reviewer found it awkward to get a secure grip on at first, though they considered that part of the training challenge (GymRadar)
