For those building a home gym in a tight space, the Goimu WM3-V4 presents an ambitious solution. This wall-mounted folding squat rack aims to combine the core functions of a power rack for heavy lifts with the versatility of a dual cable system for accessory work, all in a footprint designed to fold flat against the wall when not in use. It is engineered for users in apartments, garages, or basements who need to maximize a multi-purpose room. Bottom line: The WM3-V4 is a feature-dense, space-efficient home gym hub that prioritizes flexibility and total-body training capability over a massive, permanent footprint.

Design and Build
The Goimu WM3-V4’s design is fundamentally driven by its space-saving mission. Constructed from alloy steel, the rack’s black and red frame is built to support a significant load, with a maximum weight recommendation of 2000 pounds. The wall-mounted nature is its defining characteristic; it is not a free-standing cage. This dictates a critical prerequisite: it must be anchored to a concrete wall or solid wood studs to ensure the stability necessary for safe heavy lifting. The engineering focus is on the patented locking mechanism that allows the unit to fold to a mere 4.3 square feet, protruding only 11.9 inches from the wall, and expand to a 12.3 square foot workout station.
Physically, the design incorporates multiple training stations into one unified structure. The main uprights serve as the power rack section with adjustment holes for J-hooks and safety arms. Above, a detachable pull-up bar is integrated. The dual independent pulley systems are mounted on either side, each with its own cable and carriage. The overall build is described by owners as sturdy and solid for the price point, delivering a feel of safety when racking weight. The visual presentation is modern and functional, fitting a home gym aesthetic without attempting to mimic bulky commercial equipment.
Performance and Features
Space Efficiency and Folding Mechanism
This is the WM3-V4’s primary selling point. The ability to collapse the unit against the wall transforms a dedicated workout area back into a usable living space, a key advantage for apartments or garages that serve multiple purposes. The transition between folded and deployed states is reported to be smooth once mastered, using a tool-free quick-pin system. The mechanism is designed not to compromise stability; when locked open, the rack is intended to feel secure with no wobbling, requiring no recalibration after unfolding. This feature directly enables the “multi-use room” scenario many home gym enthusiasts require.
Dual Independent Pulley System
The dual 1:1 ratio cable machines are a standout feature that significantly expands the rack’s utility beyond basic squatting and benching. Each pulley operates independently, allowing for simultaneous workouts by two users, which is ideal for partner training or efficient supersets. The pulleys offer 15 adjustable height positions, providing a wide range of motion for exercises like lat pulldowns, tricep pushdowns, cable rows, and flies. User feedback confirms the pulleys glide smoothly without sticking, providing a consistent resistance feel. It is noted, however, that the cables may have a limited range of motion from the lowest setting for certain overhead movements, and with heavy weights, the plates might not travel the full distance before hitting the floor, a minor trade-off for the compact design.
Five Adjustable Function Modes
Versatility is engineered into the WM3-V4 through its five configurable modes. These include a fully Folded mode for storage, a Semi-Open mode for quick access, a Power Rack mode for squats and bench presses (using the safety arms), a Functional Trainer mode for single-cable exercises, and a full Cable Crossover Machine mode. Switching between these modes is designed to be quick and tool-free, letting the user adapt the equipment to the day’s workout focus, from heavy compound lifts to isolation cable work. This flexibility supports the claim of enabling over 80 different exercises from one compact unit.
Load Capacity and Accessories
With a 2000-pound tension support rating, the rack is built to handle serious weight for a home gym setting. It comes equipped with key accessories like J-hooks for bar placement, safety arms to catch failed lifts, and the detachable pull-up bar. A notable convenience feature is the compatibility with both standard 2-inch Olympic plates and smaller 1-inch plates, allowing users to integrate existing equipment without adapters. While not intended for competitive powerlifting, the consensus from owners is that it provides more than enough stability and capacity for rigorous casual and strength-focused home training.
Setup, Support and Ownership
The WM3-V4 is marketed for DIY installation, with all necessary hardware and instructions included. The process involves securely mounting the main frame to wall studs or concrete, which is the most critical step for safety. Some users have noted that the instructions can be slightly complicated or contain inaccuracies in part numbering, recommending a careful, double-checked approach during assembly. Once installed, the maintenance primarily involves ensuring locking mechanisms are engaged and cables remain in good condition.
Ownership considerations include the space requirements: a minimum ceiling height of 88 inches (7’4″) is necessary, with 98 inches recommended for optimal use. The product is backed by a one-year manufacturer’s warranty. The packaging arrives in two boxes. There is no mention in the provided data of available upgrade kits or official accessory expansions from the manufacturer, indicating the unit is designed as a complete system out of the box.
What Owners Say
Owner feedback for the Goimu WM3-V4 is overwhelmingly positive, reflected in its high rating distribution where the majority of reviews are five-star. The most praised aspects are its space-saving design and solid, sturdy feel during use, which instills confidence when lifting. Users specifically appreciate the smooth operation of the dual pulley system and the overall versatility the five modes provide. The folding mechanism receives compliments for being functional once understood.
Critical notes from users are minor and focused on the setup experience, with some finding the assembly instructions challenging to follow. A few users point out limitations in the cable travel distance with very heavy plates and the aforementioned range of motion constraints from certain pulley positions. The overall sentiment is that the rack offers excellent quality and value for its price point, exceeding expectations for a home gym solution in a compact form factor.

Who Should Buy It (and Who Should Skip It)
The Goimu WM3-V4 is an ideal choice for home fitness enthusiasts who are severely limited on space but unwilling to compromise on exercise variety. It’s perfect for apartment dwellers, homeowners with cramped garages, or anyone using a room that must double as a gym and living area. It suits individuals or partners who want to perform everything from heavy squats and bench presses to cable isolation work and pull-ups without purchasing multiple bulky machines. If your goal is a comprehensive, all-in-one home gym that can be tucked away, this rack is a strong contender.
Conversely, you should skip the WM3-V4 if you lack a suitable wall for mounting (concrete or solid studs), if your ceiling height is below 88 inches, or if you prefer a permanently deployed, freestanding power cage with no setup required before each session. It is also not the best fit for those training for competitive powerlifting who require absolute commercial-grade rigidity and unlimited barbell movement patterns. For users with dedicated gym rooms and ample space, a traditional rack paired with separate cable machines might offer more specialized performance.

Final Verdict
The Goimu WM3-V4 Folding Squat Rack successfully executes its core promise: packing a remarkable amount of gym functionality into a minimal, foldable footprint. The integration of a legitimately useful dual independent pulley system with a solid power rack and pull-up bar creates a highly versatile training hub. While it demands careful installation on an appropriate wall and has some minor limitations in cable travel, these are reasonable trade-offs for the spatial freedom it provides. For the target user—someone building a serious home gym in a not-so-serious amount of space—it represents a clever and effective engineering solution.
It is not a commercial gym replica, nor is it meant to be. Instead, it carves out its own niche as a capable, space-conscious all-in-one system. The positive owner reviews underscore its value proposition: it delivers sturdy performance, smooth pulley action, and crucial versatility where it counts most—in a confined home environment. If your priority is reclaiming floor space without sacrificing a wide exercise palette, the WM3-V4 is a compelling option that merits strong consideration.
