Adjustable Plyo Box

Name: Adjustable Plyo Box
Brand: REP Fitness
Rating: 4.56 (3 reviews)

The REP Fitness Adjustable Plyo Box is a steel plyo box that swaps the usual flip-to-resize design for a twist-lock lever mechanism, letting a single 16” x 16” landing platform switch between 16”, 20”, and 24” heights in about 30 seconds. It’s built from thick steel with solid steel spring pins locking the legs in place, a rubber top for grip, and rubber feet that hold it in place on the floor. It ships fully assembled and weighs 40 lb, with a 400 lb weight capacity. Compared to REP’s own 3-in-1 Soft Plyo Boxes, it trades a softer foam landing for a more compact, heavy-duty footprint that takes up less floor space in a home gym.

Its main limitation is the lack of a 30” height option that CrossFit athletes often train box jumps at, and reviewers note its firm, minimally-padded landing surface gives a harder landing than a foam-padded box. It carries a 1-year warranty from REP Fitness.

What is a Miscellaneou?

What’s in Miscellaneous

This is the catch-all for the conditioning tools and accessories that don’t fit a single equipment class — weighted vests and plate carriers, medicine and slam balls, plyo boxes, ab mats, and the odds and ends that round out a garage gym. Items land here because their job (loaded carries, jumps, core work) cuts across the categories rather than sitting neatly inside one.

Who it’s for

Anyone filling in the gaps around the big pieces. If you already have a rack, bar, and plates, this is where you find the vest for rucking and weighted push-ups, the ball for slams and wall throws, or the box for step-ups and box jumps. Match the tool to the training you actually do — a plate carrier for conditioning and rucking, plyo boxes for explosive work — rather than buying the whole shelf.

REP’s Adjustable Plyo Box swaps the usual flip-to-resize plyo box design for a twist-lock lever that switches between 16”, 20”, and 24” in about 30 seconds — Garage Gym Reviews calls it “well-engineered and sturdy” for the price, and a head-to-head video against REP’s own 3-in-1 Soft Plyo Boxes confirms it as the more rugged, space-saving pick of the two. Build quality is the standout dimension: fully steel-legged with rubber feet that resist sliding, and it ships free and fully assembled. The weakest dimension is functionality for serious plyometric training — it tops out at 24” with no 30” option that CrossFit athletes typically train on, and its firm steel-and-rubber landing surface is a harder landing than a padded foam box.

+Functionality: adjusts between 16", 20", and 24" in about 30 seconds via a twist-lock lever mechanism (Garage Gym Reviews)
+Build quality: steel-legged construction with rubber feet that resist sliding during use (manufacturer, YouTube comparison review)
+Value: ships fully assembled and free at a sub-$200 price point with a 400 lb weight capacity (Garage Gym Reviews)
+Versatility: compact ~20"x20" footprint is a good fit for smaller home-gym spaces and doubles as a stable seat between sets (YouTube comparison review)

−Functionality: no 30" height option, which rules it out for CrossFit athletes who train box jumps at that height (Garage Gym Reviews, YouTube comparison review)
−Build quality: firm, minimally-padded landing surface gives a harder landing than a foam plyo box, and edges feel sharp when carrying it (YouTube comparison review)
−Durability: only a 1-year warranty despite the heavy-duty steel build (Garage Gym Reviews)
−Value: at 40 lbs it's awkward for one person to reposition despite its compact size (Garage Gym Reviews, YouTube comparison review)
