Horse Stall Mat Gripper

Name: Horse Stall Mat Gripper
Brand: Massenomics
Rating: 4.99 (60 reviews)

Massenomics’ Horse Stall Mat Gripper turns the classic “carry two horse stall mats into your basement gym” grip test into a purpose-built implement: a hand-assembled block cut from genuine 3/4” premium horse stall mat, clipped to a loading pin with a carabiner so it can be pinch-lifted single- or double-handed. One face is smooth and the other has raised circular nubs, and lifters pick whichever side suits their grip. Massenomics runs an official cross-gym leaderboard for it, with published rules covering hand placement, chalk (allowed) versus straps/tacky (banned), and weight verification on a scale. Independent reviewers rate it highly for build quality and novelty value, though as a niche single-purpose challenge tool it hasn’t been put through any long-term durability testing.

Reviews by source

Expert	4.99/5	60 reviews
Youtube	4.5/5	2 reviews	Jujimufu's "This Grip Record is IMPOSSIBLE to Beat?" treats it as a fun, well-executed novelty grip-strength implement ("the ultimate way to train something you hate doing") with an official leaderboard and no functional complaints; Massenomics' own short shows real challenge use with the same enthusiastic tone.

The Horse Stall Mat Gripper is a niche but well-executed novelty grip-strength tool — a compact chunk of genuine 3/4” horse stall mat, hand-assembled to clip onto a loading pin for single- or double-handed pinch-grip challenges. GymRadar’s independent user base rates it 4.99/5 across 62 reviews, with build quality (4.98/5) and value (5.00/5) as clear standouts, and video coverage (Jujimufu’s grip-record challenge) echoes the same enthusiasm with no functional complaints. The weakest dimension is durability: no independent source has put it through long-term or destructive testing, so the strong ratings reflect short-term satisfaction and novelty appeal rather than proven longevity.

+Build quality: rated 4.98/5 across 62 independent GymRadar reviews, with reviewers praising the fully hand-assembled construction (GymRadar)
+Functionality: distinct flat/smooth and raised-nub grip sides let lifters vary the pinch-grip challenge, a feature reviewers call out specifically (GymRadar)
+Value: gives gym owners the stall-mat pinch-grip challenge in a compact, purpose-built form without buying, storing, or transporting full-size stall mats (GymRadar)
+Versatility: usable one-handed or two-handed with either grip side, and ties into an official cross-gym leaderboard with published competition rules (Massenomics records page, YouTube: Jujimufu)

−Durability: no independent source has tested it long-term or under repeated heavy loading; the strong ratings reflect short-term satisfaction, not proven longevity
−Value: a single grip implement at $42.99, and the manufacturer's page has shown it sold out with only an email waitlist available (Massenomics product page)
−Versatility: a single-purpose novelty/challenge tool for pinch-grip training specifically, not a general-purpose grip or training implement (Massenomics product page)
