Level X - ALPHA GRIPZ
Level X is the highest-resistance band in Alpha Gripz’s extensor-trainer lineup – a finger-loop device that works the forearm extensor muscles (the ones that open the hand) rather than the flexors most grip tools target. It’s sold individually or as the top tier of the four-level X-treme Alpha Set (Green/Grey/Blue/Black), aimed at lifters, grapplers, and rehab users who’ve already progressed through the lower levels and want a harder ceiling. The manufacturer’s own product page lists Level X’s resistance at 70 lbs, though other retail copy for the same X-treme Set describes it as an 18 lb band – the two figures disagree by roughly 4x and neither source resolves it, so treat the exact resistance rating as unconfirmed.
Two independent YouTube reviewers who bought and used the set (both combined with lower Alpha Gripz levels, not Level X in isolation) report a consistent story: fixed, known resistance per level beats rubber-band grip trainers because the loops don’t slip off individual fingers, and both reviewers felt real forearm/extensor fatigue working up through the levels. One reviewer, a martial artist, credited a month of use with noticeably harder-to-break grips on the mats and used the tool to spot a left/right hand strength imbalance. Both reviews are tied to referral links, so treat the enthusiasm as somewhat promotional rather than fully disinterested.

Level X earns solid marks from a small but positive owner base – GymRadar’s four reviews average 4.5/5 – and two independent YouTube reviewers who bought and used the Alpha Gripz set corroborate the core pitch: fixed, known resistance per level beats a rubber band that slips off individual fingers, and working through the levels produces real, felt forearm fatigue. Functionality is the standout dimension, with both reviewers reporting noticeable grip/forearm gains after weeks of use. The weakest dimension is build quality’s documentation: the manufacturer’s own copy for Level X’s resistance rating disagrees with itself by roughly 4x across different pages (70 lbs vs 18 lbs), and both YouTube endorsements are tied to referral links, so some of the enthusiasm should be read as promotional rather than fully disinterested.
- +Functionality: two independent YouTube reviewers who used the set for weeks both report real, felt forearm/extensor fatigue and describe visible strength gains -- one credits a month of use with harder-to-break grips in martial arts training (Grapplers Graveyard, The Mighty Plantain)
- +Functionality: GymRadar's 4 owner reviews average 4.5/5, corroborating the YouTube accounts with a separate, less promotional signal (GymRadar)
- +Versatility: fixed finger loops hold position on each finger through a full rep, unlike rubber bands which slip and require constant repositioning -- both YouTube reviewers independently called this out as the key advantage over cheaper alternatives (The Mighty Plantain)
- +Versatility: four resistance levels (Green/Grey/Blue/Black) let a user progress from beginner to Level X rather than being stuck with a single fixed resistance (manufacturer)
- +Value: individual levels list at under $10-20 on the manufacturer's own page, with bundled multi-level sets available for lifters who want to progress (manufacturer)
- −Build quality: the manufacturer's own resistance-rating copy for Level X is internally inconsistent -- the product page states 70 lbs while other retail listings for the identical set describe it as 18 lbs, a roughly 4x discrepancy that neither source resolves
- −Durability: no long-term wear data from any source -- both YouTube reviews cover only the first few weeks of ownership, and no source discusses how the finger-loop material holds up over time
- −Functionality: both independent reviews are tied to referral/affiliate links, so their positive framing should be discounted somewhat as promotional rather than fully disinterested
- −Value: coverage is thin overall -- one editorial review (Grapplers Graveyard's written article) was inaccessible and no Reddit or forum discussion of this specific product turned up, so the 4.5/5 GymRadar average rests on a small sample
