About MX Select

MX Select offers compact strength-training equipment, primarily adjustable weight systems intended to replace traditional free weights with space-efficient alternatives.

A key innovation within the brand’s lineup is its patented rapid weight change system, which enables you to adjust resistance levels through a dial-based selection mechanism rather than manually adding or removing weight plates. This system functions through a cradle-based design where the full set of weight plates remains housed, and only the selected plates are engaged during lifting.

The brand organizes its offerings across dumbbell and barbell systems, supported by accessories like adjustable benches, stands, and magnetic increment plates. Its EVO MX line features a more advanced range with variations in handle design, including contoured and knurled options. Meanwhile, the standard MX Select line provides similar functionality with slightly simplified configurations.

MX Select Offerings

1. Dumbbells

   The MX Select offers adjustable dumbbell options such as the EVO MX55, EVO MX70-100, and EVO MX100, each available with either a contoured handle or a knurled handle. The contoured handle is shaped to fit more naturally in your hand, which may help reduce grip fatigue and improve comfort during longer sets. The knurled handle has a textured surface that can improve grip security, especially during heavier lifts or when your hands become sweaty, helping you maintain better control through each movement.The adjustable design allows you to change resistance within one dumbbell set instead of switching between multiple fixed weights, which can make workouts more efficient and easier to structure. The weight distribution is designed to keep the load balanced, which may help support smoother movement patterns and reduce unnecessary strain on your wrists and shoulders.

2. Dumbbell Stand

   The Dumbbell Stand is designed to support EVO MX Select dumbbells. Its wide-base structure lets you position yourself directly over the dumbbells during lift-off, which can help improve balance and alignment at the start of each movement. This setup may reduce awkward reaching or twisting, making exercises feel more controlled and lowering unnecessary strain on your back and shoulders.Built from powder-coated steel with rubber feet, the stand is designed for durability and floor stability while helping limit movement during use. It has a footprint of 30.59” L x 21.18” W x 30.83” H, making it compact enough for home setups while still keeping the weights at a more accessible height.

   The stand arrives flat-packed and is assembled by bolting on the rear leg, top cross brace, and dumbbell cradles, which keeps setup straightforward. The total system weight reaches 166.69 lbs with EVO MX55 dumbbells and 258.38 lbs with EVO MX100 dumbbells, offering a stable storage and lifting station without taking up the space of a full rack.

3. Magnetic Increment Plates

   The Magnetic Increment Plates are add-on accessories designed for the MX SELECT Rapid Change Dumbbell System, including the EVO MX55, EVO MX70-100, and EVO MX100. They use rare-earth magnets to attach securely to the recessed areas of MX EVO handsets, which helps keep the added weight stable during lifts.The standard MX SELECT system offers 10 weight levels in one compact unit, and adding the MX Magnetic Increment Plates expands this to 20 weight options for finer load adjustments.

   The MXDIW1.25 set includes four 1.25 lb plates and two holders that fit MX EVO cradles for use with EVO MX55 dumbbells, while the MXDIW2.5 set includes four 2.5 lb plates and two holders for EVO MX70-100 and EVO MX100 models.

4. Adjustable Training Bench

   Adjustable Training Benches support a range of seated, flat, decline, and incline exercises. The brand offers an Adjustable Training Bench and MX Bench, which provide six backrest positions, from a slight decline at -5 degrees through flat to multiple incline settings up to +85 degrees, helping you adjust your body position for presses, rows, and other supported movements. Their extra-long backrests and wide lumbar support are designed to improve comfort and help keep your back more stable during longer or heavier training sessions.As per the official website, both benches use steel frames for structural support, with powder-coated finishes in silver or black, depending on the model. The MX Select Adjustable Training Bench uses antimicrobial fabric upholstery, while the MX Bench uses textured fabric, and both materials are designed to help resist bacteria, mould, mildew, and other microbes while also improving grip and surface comfort. The shaped backrest adds support across different angles, and the front-leg handle activates rear transport wheels when lifted, making it easier to reposition the bench safely without lifting the full frame.

MX Select Advantages

1. Design and Aesthetic‑Focused Engineering

   MX Select claims to combine mechanical innovation with a consistent, commercial‑grade visual identity. The brand centers its engineering around a patented double‑locking rack‑and‑pinion system, which it positions as a more secure and refined alternative to traditional selector‑pin or dial mechanisms, while eliminating loose plates and external parts. This system is used consistently across products like the MX30, MX55, MX85, and MX100 dumbbells and barbell systems. It also emphasizes aesthetic consistency through nylon‑coated steel plates, precision‑machined handles, and finishes designed to resemble fixed gym equipment rather than typical home gear. The brand also claims to focus on space efficiency, with systems designed so one unit can replace multiple fixed dumbbells or barbells within a compact footprint. This means you get equipment that feels more premium, organized, and visually aligned with commercial gym standards, while taking up significantly less space. The integrated system can make weight changes smoother and reduce clutter, which may simplify your workout flow.

2. Maintenance and Repair Positioning

   MX Select demonstrates a serviceable hardware and repair ecosystem, with a product design philosophy centered on long-term maintainability. Across models such as MX55, MX70, and MX100, the brand supports a standard 2-year limited warranty and an accessible repair framework, including official service guides, modular construction, and readily available replacement components.While the standard warranty excludes drop-related damage, the brand provides optional paid coverage upgrades and low-cost replacement parts. This highlights its structured warranty protection combined with user-accessible repair options. This means you’re not locked into replacing the entire unit if something goes wrong. If damage occurs, especially outside warranty conditions like accidental drops, you can often repair the equipment yourself using inexpensive parts and basic tools. This could reduce long-term ownership costs and downtime compared to non-repairable systems, giving you more control over maintenance and product lifespan.

MX Select Limitation

1. Niche Market Recognition

   MX Select highlights a limited presence in mainstream retail and large-scale marketplaces. The brand does not work through broad consumer platforms, which restricts its visibility in common shopping environments. Thus, discovery is less organic. MX Select is not typically encountered through casual browsing, mass advertising, or general fitness equipment searches. Awareness tends to come through deliberate research and industry familiarity within more informed fitness communities.Finding the brand may require more effort compared to widely distributed fitness brands. You are less likely to come across it while browsing major retailers or comparing options casually, creating friction in accessibility and awareness, especially if you prefer easily discoverable, widely reviewed options.

MX Select Alternatives

1. NUO

   NÜO keeps its product ecosystem focused on adjustable dumbbells, while MX Select builds out a broader home strength setup with multiple equipment formats.As per its official website, its lineup centers on the NÜOBELL and NÜOBELL S series, with options such as the NÜOBELL 550 that adjusts from 5 to 50 pounds, the NÜOBELL 580 with a 5 to 80 pound range, and the NÜOBELL S 5100 that reaches 100 pounds. Its system also includes accessories built specifically around those dumbbells, such as the standard floor stand, the height-adjustable NÜOBELL S Pylon Floor Stand, and expansion kits that let you increase the weight range without replacing the main set. MX Select, in comparison, spreads its range across both its classic and EVO systems. Its catalog includes MX30, MX55, and MX85 dumbbells in both contoured and knurled handle options, EVO MX55 and EVO MX70–100 dumbbells, EVO MX100 models, and MX100 barbells. It also features the EVO MX125 knurled barbell rack system, adjustable benches, magnetic increment plates in 1.25 and 2.5 pound options, impact pads, and add-on kits. This gives MX Select a broader equipment mix, while NÜO stays more focused on refining the adjustable dumbbell experience.

   NÜO describes NÜOBELL as a compact, on-demand system that lets you switch resistance instantly without breaking workout flow, making it easier to move between exercises, supersets, and drop sets in limited space. Its messaging emphasizes sleek matte black and silver finishes, minimal footprint, and a setup that can blend into a home environment rather than feel like bulky gym gear. On the other hand, MX Select focuses more directly on the mechanics of rapid adjustment. It highlights that its patented system uses a weight plate cradle with a side release button and pop-up selector dial. To change weight, you place the handset in the cradle, press the release button, turn the selector dial to the desired setting, lock it back into place, and slightly raise the handset to confirm that the intended plates are engaged. While both brands prioritize fast transitions, NÜO presents that convenience as part of a smoother workout experience, whereas MX Select highlights the structured functionality of its mechanism.

   The two brands also differ in how they support training progression and workout variety. NÜO concentrates on making dumbbells feel balanced, compact, and intuitive for everyday strength work. Its expansion kits allow you to build on your existing setup, while its stands are designed to improve storage and make racking more ergonomic. MX Select, on the other hand, gives you more ways to build a fuller strength setup from the start. It also supports barbell training, bench work, and micro-loading through magnetic increment plates, which can be useful if you want more exercise variety or more precise progression without relying on separate brands.

   According to their official website, NÜO feels more design-conscious and lifestyle-integrated. Meanwhile, MX Select offers a broader strength ecosystem with more equipment variety and training flexibility.

2. REP Fitness

   As per its official website, REP Fitness is built for people who want a full gym setup, while MX Select focuses on compact adjustable systems that reduce clutter. REP’s catalog stretches across racks and rigs, cardio, benches, bars and weights, cable machines, accessories, apparel, and nutrition, making it a broader training ecosystem. On the other hand, MX Select keeps its lineup much tighter, centering on rapid-change dumbbells, stands, and add-on plates for people who want fewer pieces of equipment taking up space.REP Fitness offers more depth if you want variety in your workouts. Its strength range includes the PR-5000 and PR-4000 rack systems with crossmembers, weight horns, spotter arms, dip stations, flip-down safeties, pull-up bars, and logo plate crossmembers. It also carries multiple adjustable bench options such as the AB-3000 2.0, AB-3100, REP Nighthawk, and BlackWing benches. On the free weight side, REP covers hex dumbbells up to 125 lb, Ergo Hex dumbbells, adjustable kettlebells, resistance bands, sandbags, and plyo boxes. In comparison, MX Select is far more specialized. Its core products revolve around MX30, MX55, and MX85 dumbbells, along with the EVO series, such as EVO MX55, EVO MX70-100, and EVO MX100, available in both contoured and knurled handle options depending on grip preference.

   TAs per the training convenience offered, REP Fitness supports building out a gym with separate equipment for different lifts and movements. Its product lineup also includes cable attachments like tricep ropes, D-handles, ankle cuffs, multi-grip curl bars, gymnastics rings, and landmine attachments. Meanwhile, MX Select focuses on simplifying setup and storage. Its patented double-locking rack-and-pinion rapid weight change system is designed to replace multiple pairs of dumbbells or barbells with one adjustable setup. The brand specifically highlights that its system can reduce the need to store 10 pairs of dumbbells and racks, or 26 separate barbells across multiple racks.

   REP also puts more emphasis on build-to-order options, service, and ownership support for larger purchases. Many of its benches, racks, and accessories come in multiple finishes such as metallic black, matte black, red, blue, white, clear coat, and army green. The brand backs this with free shipping on all orders, financing options, assembly services, spare parts access, warranty support, local pickup, and showroom locations in California and Pennsylvania. On the other hand, MX Select’s support is more focused on product maintenance and system ownership, with product registration, warranty service, part requests, and distributor location support rather than broader setup services. Another area where REP expands beyond equipment is recovery and nutrition. Through its Purist line, REP also offers NSF Certified Sport whey protein, pre-workout, hydration powder, creatine, and protein bars. The brand highlights no artificial ingredients, third-party testing, plastic-neutral certification, and packaging made with at least 30% post-consumer recycled plastic. MX Select does not branch into related wellness products, staying focused entirely on adjustable training hardware.

   REP Fitness offers a full-featured home gym support with more equipment categories, training variety, and expansion potential. MX Select prioritizes saving space and switching weights quickly through a more compact adjustable system without filling your room with separate dumbbells, barbells, and racks.

How Did We Evaluate?

1. Real User Feedback

   We analyzed real user experiences of MX Select and its offerings across Reddit threads and discussions based on reviews across 2026. Feedback reflects a mix of practical usability advantages and noticeable design trade-offs.Many users described the brand’s adjustable dumbbells as a space-efficient and cost-conscious choice for home gyms. Users frequently highlighted the quick-adjust mechanism and open-handle format as convenient during workouts, with some users describing a smoother and more natural feel compared to selector-pin systems.

   Based on the available feedback, the brand delivers functional convenience and value for most users, but with recurring concerns around fit, finish, and handling consistency. The experience appears acceptable for general use, but less aligned with expectations of precision-focused or highly experienced lifters.

2. Brand Reputation

   While evaluating MX Select, we analyzed the brand’s core positioning and ratings across independent review forums. The brand presents itself as a relatively modern, product-focused brand, with its reputation shaped more by engineering convenience and home-gym adaptability than by a long-standing legacy.On TenereTeam, the brand carries a 4.3 out of 5 score based on a limited number of reviews shared across 2025. The reviews highlight consistent recognition for durable metal construction, precise weight adjustment, and ergonomic handling. However, repeated concerns around the wide, diagonally slanted plate design point to balance issues during certain exercises, along with sensitivity in the adjustment mechanism that required careful handling.

   Currently, the brand’s visibility remains limited across other independent platforms such as Trustpilot, Better Business Bureau, and ThingTesting. The brand reflects a functional, niche-oriented positioning rather than a widely recognized or consistently verified reputation.

Frequently Asked Questions

1. Can MX Select’s adjustment mechanism impact flow during fast-paced training?
   It is possible. The brand uses a dial-based locking system that keeps plates secure during sets, so movement is generally stable. However, the brief pauses required to adjust weight between sets may impact workout flow, especially if the dial is not fully engaged or adjusted mid-set.
2. Are MX Select dumbbells durable enough to withstand repeated dropping?
   No. The dumbbells use metal components such as steel plates and a selector system, which might tolerate occasional accidental drops. However, the makers advise against repeated or intentional dropping, which might damage the mechanism and affect warranty coverage.
3. Can MX Select systems require more setup time than fixed weights?
   Yes. Changing weights requires returning dumbbells to the cradle, engaging the release, and adjusting dials on each end. This adds time compared to picking up fixed weights. Initial setup, like cradle alignment, may also be needed.

Conclusion

MX Select is built around adjustable dumbbell systems intended for compact storage and quick weight changes. The brand’s offerings emphasize space efficiency and modular expansion, making it suitable for controlled indoor training setups.

However, the brand’s reliance on a wide, diagonally slanted plate design might affect balance during lifts, sometimes creating uneven weight distribution and requiring grip adjustments. Certain movements, such as upright rows or exercises involving close body positioning, may feel restricted due to plate width.

When considering the brand, it is essential to account for the brand’s reliance on mechanical adjustment systems, which often require proper handling and familiarity. Your experience with its offerings may depend on training style, handling comfort, and expectations around durability.
