SC2 Stair Climber Machine Ultra

I turn 40 later this year. If I could go back and do one thing different in my fitness journey, I would have started doing cardio much earlier. We found the SC2 Stair Climber Machine Ultra and fingers crossed, toes crossed, everything crossed, that this is the cardio piece we’ve been searching for. After handling multiple rowers, air bikes, elypticals, treadmills and more, I have a good feeling that the search is over.

The FED Fitness SC2 Stair Climber Machine Ultra is now on the Review Pipeline.

FED Fitness SC2 Stair Climber Machine Ultra Overview

When we started getting serious with cardio, we had this itch to get a Stair Climber. I actually had a company ready to work with me, but then we measured and the machine wouldn’t fit. I was bummed. But we want back to the search. My daughter has been asking for a stair climber, my wife has been asking for one, and I would have bought one, if we could have found one that met our needs.

Then FED Fitness reached out and offered a brand new piece they were working on, the SC2 Stair Climber Machine Ultra. I assumed it would be another shiny toy I couldn’t have, but the tagline “Commercial-Grade, Home-Friendly Size” had me instantly intrigued. I grabbed my tape measurer and ran out to the backyard to measure. IT WOULD FIT! I measured again, and another time just to make sure. I sent off the email, and a few weeks later it arrived.

If you can’t tell, the biggest selling point here, for us, is the size. Most stair steppers have 4 or 5 steps, which is awesome and gives you some additional workout options, but it makes for a VERY tall workout, meaning that this 6ft tall dude standing under an 8ft tall covered patio, wasn’t gonna work.

The SC2 Stair Climber Machine Ultra has essentially 3 working steps at a time, which cuts down close to 2 feet of required head space. It is also fairly narrow, meaning it would fit well on our back patio without taking up the entire place. We still wanted room for one more cardio piece back there, and this was a perfect solution to do so.

The SC2 Stair Climber Machine Ultra is also rated to work with athletes around 45lbs (my daughter is around 65lbs currently) and up to almost 400lbs, so it should work for the entire family as well as all of our friends and athletes in and out of our space. With the adjustable speeds, programs, safety features, and more, we’ve got a product that my mom can use, my daughter can use, I can use, you name it. This thing was checking a LOT of boxes for our backyard cardio corner.

Shipping & Assembly

The SC2 Stair Climber Machine Ultra arrives in one large box, on a cardboard pallet. If you plan to put it into the garage, this is a fairly simple process. Unbox it, wheel it out into place, and then assemble. Since I needed to go through my front door, through the living room, out the back door, and into the back patio, things were a little different.

To get the box off the pallet, you have to cut the straps. Those straps, unfortunately, keep the main box attached to the bottom insert. Which means you are going to be working with a less than stable box as you maneuver into place. The box fit through all of my doors, but it was VERY close on a couple of them. And it weights over 300lbs, so even though I regularly deadlift well over 500lbs, this was an interesting task.

There are no handles, no straps, nothing, to help you maneuver this. I got there, but it was an experience for sure. Ideally, I think the team would add some straps, handles, something to help get this from Point A to Point B. Also, if you are reading this, the main frame itself has wheels (I didn’t know this). So you can take it all out, attach the steps on the outside, use those as handles, and wheel the entire thing to where you need to take it. Then finish assembly, and be good to go. If I ever had to do this again, I’m pretty positive that would be my plan.

On a brighter note, they did a FANTASTIC job of packing the SC2 Stair Climber Machine Ultra. The inserts were molded perfectly to the box, which had absolutely zero wiggle room, and everything was in perfect condition. It was delivered by freight, so that helps too. Keep that in mind by the way, depending on your driveway and access points.

The majority of the SC2 Stair Climber Machine Ultra comes fully built, you need to add on the outside steps, the handrails, monitor and dash. They do a great job of zip-tieing all appropriate cables for easy installation, and anytime we have more than one cable assembly in a single spot, they made sure to make them different sizes so you couldn’t cross any wires. You need to install the plastic covers over the wire ports with a screwdriver, and you are done.

Moral of the story here, while this is meant for a home gym, it is heavy and large and not the easiest set-up I’ve ever done. You likely need a couple people to help get it into place, assembled, and ready for work. Or one 250lb stubborn dude with a little creativity.

FED Fitness SC2 Stair Climber Machine Ultra Features

The SC2 Stair Climber Machine Ultra plugs into a basic power outlet, has a full touchscreen monitor alongside multiple button options for controls, a number of safety features, monitoring, programs, and more. Lets dig into those briefly.

Overall Build

The SC2 Stair Climber Machine Ultra was much heavier and more robust than I thought we were getting. In a good and bad way. Luckily I’m a large dude, so moving it around and into the right position was easy (ish). For smaller, more normal human beings, you’ll need to consider this. I’ll make sure to have my wife and maybe daughter try and move it around. It was heavy enough that when we rolled it on the wheels, it kept smushing the interlocking mats we have together and creating a problem. Make note of that depending on your flooring choices.

The steps have a textured pattern to them, with an initial test seeming to be solid. I’m glad it isn’t grip tape, but also glad it isn’t just flat. Hopefully a good balance regardless of what footwear we put on.

The majority of the SC2 Stair Climber Machine Ultra frame is your typical plastic housing for cardio equipment. With how much action this gets, we’ll see if we have any issues over time.

A couple notes on the build. The monitor sticks out the back ever so slightly from the frame, which unfortunately, if you are sliding it up against a wall, eats a few inches of space. I think they should make it all flush. Just like with the FED treadmill we used, the included power chord is fairly short. It at least isn’t just one direction, but I think a bungee power chord, or even just providing an 8-10ft chord would the ability to wrap up tightly would be nice. I always seem to be JUST shy on length.

I mentioned the flooring moving on me during installation. I bet this is because the wheels are small. I’ll need to confirm for the final review, but typically large wheels displace their weight better and don’t cause issues like this. While we don’t plan to move this around very often, the occasional move for cleaning would be ideal, and I’d like to not mess up the floor every time.

Safety Features

With a treadmill we often have a safety strap. With a stair climber we often have a few other options. The SC2 Stair Climber Machine Ultra has an emergency stop button on the main dash, on the touchscreen, on the handlebar, on the frame, and has two infrared stops at the top and bottom of the last step as it begins to roll underneath the frame.

I’m glad we have a few options, but that honestly almost feels like too many. Infrared is on point, worked perfectly multiple times, and does what it needs to do. The button on the side is a great easy option for a spotter/coach as needed. And I think having a big red button on the center dash makes sense. The touchscreen seems unnecessary, and the extra stop on the handle does as well. I’ll see if this causes any issues as we go, but having multiple buttons that do the same thing for the machine feels clunky.

Monitor & Programs

The SC2 Stair Climber Machine Ultra has a LARGE monitor, and I am here for it. It doesn’t do anything fancy, so we won’t be watching TV shows or anything here unfortunately, but it is easy enough to see everything at one time. The screen is a touchscreen, specifically for the buttons towards the bottom row. With the fact that we have the buttons themselves right below that, I don’t know that we’ll use the touchscreen that often. But time will tell.

Compared to a number of other cardio machines we have used, this is the cleanest, brightest, easiest to navigate screen so far. It has 6 different basic programs that rotate through variances in the difficulty/speed. It also has a manual setting, an interval setting, and a fat burning mode. Not positive what the last two are yet, but we’ll likely spend most of our time in the manual mode.

We also get our time, heart rate, calories, and other metrics on screen here. AND we get to adjust for our athletes bodyweight. From what I’ve read, there is a way to create profiles. So we’ll need to tinker with that. Quick note here, the SC2 Stair Climber Machine Ultra is rated for 44lb up to 397lbs. The machine defaults to metric (so kilos), I’m hoping we can change that in a settings somewhere.

But we also found that the 44lb isn’t accurate. My daughter weighs 65lbs, and the machine would not operate. We tried a number of different settings, even dropping the weight down to 44lbs, and it wouldn’t work. When we added a weighted vest, it worked. My vest weighs 30lbs, so we need to do some additional testing here to dial it in, but 44lbs ain’t it.

Controls and Other Features

You are probably going to spend a lot of time holding onto the handle bars of the SC2 Stair Climber Machine Ultra, so I’m glad each of them has controls for pausing, starting, upping and lowering the speed, as well as the heart rate monitors. At first glance these seemed a little “in the way”, but in use that doesn’t seem to be the case.

The main dash has a phone charging station. This appears to be a better solution than the one we had on the treadmill that bopped around too much to work. I’m still not positive if it is at the correct angle for viewing during activity, but we’ll see as we go.

On top of that, we have two power ports on the side of the monitor, USB-A and USB-C ports. I don’t think we’ll be using that to charge anything, anytime soon. BUT, I think they might be the perfect solution for adding a powered fan to the top of the monitor. I found myself already wanting just a little bit of fresh air to help cool me down in use.

Oh, and the SC2 Stair Climber Machine Ultra has this cool blue LED accent lighting on the main body and inside the chains of the steps. We put ours on a remote for power, since it is right outside our bedroom window, just to make sure we didn’t have any funny business. But the accent lighting is nice. I’ll try and get some night shots.

What I’m Looking For In The FED Fitness SC2 Stair Climber Machine Ultra

First, is gut checking all of the basics. Will the SC2 Stair Climber Machine Ultra work for me, my wife, my daughter, and everyone else. Is it strong enough, fast enough, slow enough, easy enough to use? It is safe, is it sturdy, you get it. My daughter has been around gym equipment her entire life, with the safety features here, I should be able to let her go at it unsupervised and be fine. And the same goes for me hitting a hard cardio session. I don’t want to see me taking a tumble.

We have had some mixed experiences with FED cardio equipment so far. Since I am 6ft 250lbs, I put some stress on lighter load equipment. Being a home gym piece, being smaller, being lighter, the SC2 Stair Climber Machine Ultra is going to need to still work well for my size.

It is going to live outside on the back patio, so it is going to see 100+ degree days, and eventually cold days as well. Can it keep up? Will that introduce any issues?

I plan to use this myself five times a week, alongside my wife at three or four, my daughter will tinker, and I’m hoping my mom will hop on twice a week. We’ll add in a few others here and there, but we are looking at close to 10 sessions a week. Is this home gym piece ready for that amount of work?

I’ll be testing the programs, the accuracy of the measurements, and figuring out how well the monitor and charging station work. Previous FED pieces lacked in these departments.

Along the way we’ll find some more hiccups, insights, and items as we go.

Other Options On The Market

STEPR offers an at home solution, but we’ve personally had some hiccups with their team, and I’ve received a number of DMs and emails from people who regret buying their equipment. Their owner No-Showed on a commitment over on r/HomeGym, then tried to pass it off as me not doing my job to communicate well. Too many red flags from them, that keeps me from going that route.

Otherwise, I wasn’t personally able to find another at-home suitable stair climber machine. I’m sure they are out there, and more will come, but I didn’t find them. So in terms of what the SC2 Stair Climber Machine Ultra offers, I don’t see anything else I would personally recommend even from an initial glance.
