Is the Sole ST90 the right fit for your home gym? Let’s find out together.
In a Nutshell
Here’s the quick scoop on the Sole ST90 before you dive deeper:
-
Built like a tank: This machine weighs 375 lbs, so it stays rock solid during tough sessions. No wobbling, no shaking.
-
Smooth and quiet operation: You get a calm workout experience. No loud motor noise to disturb your home.
-
Grippy footrails give your feet extra support. You feel secure even during intense climbs.
-
Assembly is simple. You won’t spend hours with tools and confusing instructions.
-
Customer service shines here. The support team actually helps when you need them.
-
Heads up though: this machine has a large footprint. You need dedicated floor space for it.
-
Moving or relocating the ST90 is tricky. Its heavy frame makes it a poor choice if you plan to shift it often.
-
Compared to options like Jacob’s Ladder or generic stair steppers, the ST90 offers a different climbing feel. Each machine has its own strengths.
Bottom line: The Sole ST90 suits people who want a permanent, gym quality stair climber at home. It’s not for anyone needing a portable or compact machine.
Build Quality and Design
The Sole ST90 feels like a professional gym machine sitting in your home. Every component reflects solid engineering choices that prioritize durability over shortcuts.
The frame construction uses heavy duty materials that absorb impact without wobbling. This stability matters when you’re pushing hard on those steep inclines. The machine’s substantial weight of 375 lbs actually works in your favor here. It stays planted firmly to your floor, eliminating the bounce and sway you get with lighter models.
The slat belt deck design sets this climber apart from basic steppers. Instead of a solid platform, individual slats move independently beneath your feet. This creates a more natural climbing motion that mimics real stairs better than flat surfaces. Your joints experience less jarring impact because the deck absorbs force more intelligently.
Foot placement gets real attention too. The grippy footrails wrap around your feet with textured surfaces that prevent slipping. Whether you’re climbing fast or tackling steep angles, your feet stay secure. This design detail prevents the frustration of your feet sliding around mid workout.
The touch screen display measures 25.6cm across and sits at eye level. You see your stats without straining your neck. The screen feels responsive and intuitive, showing metrics clearly during intense sessions.
Assembly happens faster than you’d expect for a machine this size. Most users report finishing setup in under an hour with basic tools. The instructions make sense, and parts fit together logically. Sole’s customer service team backs you up if questions pop up during assembly.
One design trade off exists: the ST90 occupies significant floor space. This isn’t a machine you tuck into a corner. You need dedicated room for it. Once installed, moving it requires serious effort due to its weight and size. This machine works best as a permanent fixture in your workout space.
The overall design philosophy here is clear: build something that lasts and performs like commercial equipment. Sole chose durability and functionality over compact convenience.

Display and Touch Screen Technology
The touch screen on the ST90 measures 25.6cm and delivers what you need during your workout. This display sits at eye level, so you don’t have to crane your neck or look down constantly. The screen shows your essential metrics without overwhelming you with clutter.
The interface responds quickly to your touches. You can adjust settings mid workout without losing your rhythm. The responsiveness matters when you’re climbing hard and sweating. A slow screen feels frustrating, but the ST90 keeps pace with your intensity.
Real world use shows the display holds up well. The screen resists fingerprints better than many machines in this category. Sweat and moisture don’t cause glitches or unresponsive areas. This durability counts because you’ll be gripping the handles and touching the screen during sessions.
Navigation through workout programs feels intuitive. You won’t need to read a manual repeatedly to find basic functions. The menu layout groups similar options together logically. Whether you’re a first timer or a regular climber, you can jump into a session quickly.
The display tracks your climbing data consistently. You see real time feedback on your incline level, step count, calories burned, and time elapsed. This information helps you push harder or pace yourself appropriately. Some users appreciate the ability to save workout history to monitor progress over weeks and months.
One consideration exists around screen brightness. In rooms with strong natural light, you might need to adjust the angle slightly to see the display clearly. The brightness itself is adequate for most home gym spaces. If your workout area gets direct sunlight, you may want to test this before committing.
The touch screen technology on the ST90 balances functionality with durability. It doesn’t try to do too much. Instead, it focuses on delivering the information you actually use while climbing. This straightforward approach keeps the machine reliable and your workouts uninterrupted.
Performance and Workout Experience
The Sole ST90 delivers a workout experience that feels like stepping into a commercial gym. Your legs engage intensely as you climb against the machine’s smooth resistance, and the 15% maximum incline pushes your cardiovascular fitness to new levels. This steep angle makes every session genuinely challenging, whether you’re a beginner or an experienced climber.
Your body stays stable throughout the workout. The grippy footrails keep your feet anchored, so you can focus purely on climbing without worrying about slipping. The frame absorbs your weight and impact smoothly, creating that premium gym-quality feel that home machines rarely match.
The slat belt deck design works differently than basic steppers you might find elsewhere. Instead of traditional pedals, this design mimics real stair climbing more closely. Your feet land naturally, and the motion feels organic rather than mechanical. This setup reduces strain on your joints while maximizing muscle engagement in your glutes, quads, and calves.
Quiet operation keeps your workout peaceful. You won’t hear loud grinding or squeaking sounds that distract you or bother others nearby. The machine runs so smoothly that you can watch the display, listen to music, or focus on your form without noise interruptions.
The touch screen display sits at eye level and responds quickly to your inputs. You can adjust incline levels mid workout, monitor your climbing data, and track progress without fumbling with buttons. The interface stays intuitive, so you spend more time climbing and less time figuring out controls.
Daily use feels sustainable on this machine. The challenging incline doesn’t feel overwhelming once you build your routine. Your muscles adapt, and the consistent resistance helps you see real fitness improvements over weeks and months.
One thing to note: longer sessions can fatigue your lower body significantly. This is actually a positive sign. It means the ST90 delivers the intense, effective workout you’re seeking. If you want a stair climber that performs like commercial equipment and keeps you engaged, this machine proves itself during every session.

Assembly and Setup Process
The Sole ST90 arrives as a complete package, but getting it ready for your first workout requires some planning. The machine weighs 375 pounds, which means you’ll want help during the unboxing and positioning phase. Clear a large area in your workout space before the delivery arrives.
Assembly moves faster than you’d expect for a machine of this size and weight. Most users report completing the setup in under two hours. The instruction manual provides clear step by step guidance. You’ll connect the frame sections, attach the footrails, and secure the slat belt deck in place. The touch screen display installs last and requires careful alignment to sit properly at eye level.
The heavy frame construction actually works in your favor during assembly. Each component fits together with precision, so parts align easily without forcing or adjusting multiple times. The grippy footrails attach securely and don’t shift during installation.
One major consideration exists: placement matters significantly. The ST90 occupies a large footprint, and its 375 pound weight makes relocation difficult once positioned. Measure your space carefully before assembly begins. Ensure doorways are wide enough for the machine to pass through. Many users keep the ST90 in one permanent location rather than moving it frequently.
The base sits flat and stable on most floor types. Carpet works fine, though some users prefer hard flooring for better stability during intense climbs. Ensure adequate ventilation around the machine since you’ll generate heat during workouts.
Once assembly completes, the touch screen powers on and guides you through initial setup. You’ll connect to WiFi if desired and create your user profile. The display responds quickly during this process and confirms all systems are functioning properly.
The overall setup experience reflects the commercial grade design philosophy. Everything feels solid and purposeful. You’re not dealing with flimsy parts or confusing instructions. The machine communicates confidence from the moment you begin assembly. After setup finishes, you have a professional gym quality stair climber ready for daily use in your home.
Space Requirements and Portability
The Sole ST90 weighs 375 pounds, which shapes every decision you make about placement. This substantial weight means you cannot treat it like a typical home gym machine that you move around freely.
Your floor needs to support this machine permanently. Once you position the ST90, moving it requires serious effort and planning. Most users find a dedicated space works best because relocation becomes impractical after initial setup. The machine sits firmly on any standard floor type, but you should verify your floor can handle concentrated weight in one area.
The footprint itself demands attention before you buy. The ST90 occupies significant floor space, so measure your room carefully. You need clearance not just for the machine itself, but also space around it for safe entry and exit. Your climbing motion requires comfortable positioning, so cramped corners won’t work well.
Portability essentially does not exist with this machine. Unlike lightweight steppers or folding cardio equipment, the ST90 stays put. This actually works in your favor for stability during workouts. The heavy construction prevents wobbling or shifting as you climb, which keeps your movement smooth and controlled.
Plan your space layout before delivery arrives. The machine needs a path into your home during installation. Narrow doorways or tight staircases can create real problems. Many owners choose a basement, garage, or dedicated fitness room where space allows for easy placement.
The sturdy base sits flat and stable once positioned correctly. You won’t need special flooring or additional supports underneath. The machine adapts to most home environments, but only if you give it adequate room.
Think of the ST90 as a permanent fixture rather than flexible equipment. This mindset helps you choose the right location from the start. Your initial placement decision becomes your long term setup, so choose wisely. The machine rewards you with reliability and smooth operation when you respect its space requirements and keep it in one dedicated area.

Who Should Buy It
The Sole ST90 works best for people who have a dedicated workout space and plan to keep the machine in one location long term. If you move frequently or live in a small apartment, this machine isn’t your best match.
Fitness enthusiasts who want serious incline training should consider the ST90. The 15% maximum incline challenges your legs and builds strength effectively. This feature suits people training for hill running or looking to increase daily workout intensity.
Home gym owners with stable floor space benefit most from this machine. The 375 pound weight requires permanent placement, so you need a room where the equipment stays put. Basements, spare bedrooms, or dedicated home gyms work perfectly for this setup.
People who value quiet, smooth operation during their workouts find the ST90 appealing. The machine runs without distracting noise, so early morning or late night training won’t disturb others in your home.
Those seeking commercial grade durability appreciate the sturdy construction. If you use your equipment daily and want something built to last, the solid frame delivers reliability. The grippy footrails and stable base support consistent use over many years.
Individuals with good upper body strength and balance handle the ST90 well. The footrails require you to hold on properly, and the steep incline demands core engagement. Beginners might find the learning curve steeper than simpler machines.
People who don’t need portability or flexibility work well with this machine. Once you place the ST90, moving it becomes impractical. Commit to your space before purchase.
Buyers who appreciate responsive touch screens and easy navigation benefit from the 25.6cm display. Quick input and clear workout tracking appeal to tech savvy users.
The ST90 suits people with realistic space expectations. You need room for the large footprint plus walking space around the machine. Measure your space carefully before deciding.
Skip the ST90 if you prefer equipment you can relocate easily or if space constraints exist in your home. Consider other options if you might move within the next few years. The machine demands commitment to permanent placement.
Final Verdict
The Sole ST90 earns its place as a serious contender for home fitness. Good customer service backs up the machine when questions arise. This support matters once you commit to such a large piece of equipment.
Compared to options like the NordicTrack elliptical or Jacob’s Ladder, the ST90 offers a different training style. It focuses on steep incline work rather than low impact movement. This makes it a good pick for people who want leg and cardio intensity in one machine.
Generic stair steppers often lack the stability this machine provides. The BowFlex Max Trainer targets a different muscle group entirely. If you want focused climbing resistance, the ST90 stands out among these alternatives.
This machine rewards patience and planning. Think carefully about your fitness goals before you decide. If steady, long term training matters to you, this climber delivers consistent results over time.
Your workout routine will benefit from the variety this machine brings. Switching between incline levels keeps sessions interesting. Boredom rarely becomes a problem with this kind of equipment.
Daily users report satisfaction with how the machine holds up over months of use. Consistent performance builds trust in the product. This reliability factor often matters more than flashy features.
Buyers who do their research before purchase tend to feel more confident. Checking your space and your fitness goals first leads to better satisfaction after delivery. Rushing into a purchase without this groundwork often causes regret later.
For home gym owners who want a machine that performs reliably and lasts, the Sole ST90 fits the bill. It serves specific fitness needs well when matched with the right environment and expectations. Careful planning turns this climber into a long term training partner rather than a source of frustration.
Overall, this climber suits dedicated fitness enthusiasts who want challenging results from a stable platform.
