MAG Medium Grip Supine

MAG’s (Max-A-Grip) Medium Grip Supine is a supinated (palms-facing-you) cable attachment built for lat pulldowns, seated rows, and weighted or bodyweight chin-ups on any cable machine or functional trainer. It’s roughly 22 inches wide (middle finger to middle finger) — MAG’s “medium” width sits between their close and wide grips, sized to work for both larger and smaller athletes. Construction is welded steel with a durable rubber/polymer coating, and the curved handle geometry lets the bar be gripped further into the pull, giving a longer range of motion at the top of a pulldown than a straight bar. Reviewers consistently note it drives noticeably more lat and bicep engagement than a straight bar, at a premium price point compared to generic lat-pulldown handles.

What is a Cable Attachment?

What cable attachments are

Cable attachments are the handles and bars that clip to a cable machine, functional trainer, or lat/row station to change the exercise — lat bars, triceps ropes, single-D handles, row/close-grip handles, ankle straps, and more. A small set of them turns one cable stack into dozens of movements.

What to look for

A rotating swivel or ball-bearing joint keeps the cable from twisting and lets the handle track your arm; comfortable, durable grips (knurled metal, rubber, or coated nylon) survive heavy use; and a standard carabiner or snap fits most machines. Match the attachment to the exercises you actually train rather than buying a giant kit you won’t use.

The MAG Medium Grip Supine is a standout cable attachment: reviewers on GymRadar (4.79/5 across 11 reviews) and independent write-ups converge on strong lat activation and no-flex build quality, with one going as far as calling it “my favorite MAG Grip by a wide margin.” Its strongest dimension is functionality — the supinated, curved handle drives noticeably more back engagement than a straight bar and adds biceps involvement on the pull. Its weakest is value, since buyers consistently flag the premium price and MAG’s refusal to run sales; a couple of reviewers also note the supinated grip can feel less comfortable than pronated for shorter arms or under very heavy loads.

+Functionality: supinated curve drives noticeably more lat and bicep engagement than a straight pulldown bar (graymatterlifting.com; YouTube reviewer)
+Build quality: commercial-grade welded steel with rubber coating, no flex under heavy loads and no wear after thousands of reps (graymatterlifting.com; GymRadar reviews)
+Versatility: works well for lat pulldowns, seated rows, and weighted/bodyweight chin-ups; sized to fit both larger and smaller athletes (maxagrip.com; graymatterlifting.com)
+Durability: no degradation reported after extensive testing, described by multiple GymRadar reviewers as more durable than knockoff versions (graymatterlifting.com; GymRadar)

−Value: premium price with no sales offered by the manufacturer, a recurring complaint across reviews (GymRadar review from Big Mark)
−Functionality: the supinated grip can feel less comfortable than pronated for shorter arms or narrower shoulders, and some report elbow irritation under very heavy loads (GymRadar reviews)
−Versatility: less range-of-motion benefit at the top position for lifters under six feet compared to taller users (graymatterlifting.com)
