Justice, Podium or Summit: Which Aviron Treadmill Is Right for You?
The short answer. Choose Justice if you want a full treadmill that folds away and doubles as a walking desk. Choose Podium if you run, or if the whole house is going to want a turn. Choose Summit if climbing is your thing, because it goes to 42 percent incline and back down to a 6 percent decline. All three run the same Aviron World platform, so whichever you pick, you get every game, race, class, scenic route and streaming app we make.
Here is the good news about this decision: you cannot get the software wrong. There is no entry-level content tier and no premium library hiding behind the more expensive machine. Justice, Podium and Summit all run the full Aviron World experience, which means more than 1,000 programs, over 300 Les Mills workouts, live head to head racing against real people, scenic routes through places you will want to see, and Netflix on the screen if that is what gets you moving today.
So this is not a good, better, best ladder. It is a pick your player moment. Three genuinely different machines, built for three genuinely different lives, and the only real question is which one matches yours. Let us find it in about four minutes.

Pick your player: four quick questions
Read down the list and stop at your first yes. That is your machine, and you can jump straight to its section.
| If this is you | Your machine | Because |
|---|---|---|
| Climbing is the workout you look forward to | Summit | Goes to 42 percent, and it is the only one that goes downhill too |
| You run, or several people will share it | Podium | 4.5 CHP motor, full 60 in deck, 350 lb capacity, and it still folds |
| You want to walk while you work | Justice or Podium | Both take the WalkDesk and turn into a standing desk |
| You want the most treadmill that fits the smallest space | Justice | Narrowest frame of the three, folds flat, best starting price |
Justice: small spaces and desk walking
Justice is the one that fits the life you already have. It runs 12.5 MPH on a 3.5 CHP brushless motor, climbs to 15 percent, and rides on a CloudStride deck with eight shock absorbers, which is a proper treadmill by any measure. Then, when you are done, one hand lifts it upright against the wall and you get your room back.
The part people fall in love with is the WalkDesk. Clip it on and Justice becomes a walking desk with a stable, level typing surface, cupholders and a tray. Walk through your morning meetings at 2 MPH, lift the desk off at lunch, run at 12.5 in the afternoon. One footprint, three machines, and a step count that quietly takes care of itself. If you have been eyeing walking pads, this is the version that also happens to be a real treadmill. We compared the two in walking pad vs treadmill.
Which Aviron treadmill is best for a small space?
Justice, and here are the actual numbers so you can measure your room with confidence before you buy.
| Model | In use (L x W x H) | Folded | Deck | Capacity |
|---|---|---|---|---|
| Justice | 80" x 34" x 66" | 53" x 34" x 68" | 20" x 59" | 300 lb |
| Podium | 80" x 37" x 66" | 49" x 37" x 68" | 22" x 60" | 350 lb |
| Summit | 67" x 37" x 71" | Does not fold | 22" x 61" | 350 lb |
Two useful surprises in there. Summit actually takes the least floor length of the three, at 67 inches against 80, so if it is getting a permanent spot anyway you come out ahead on floor space. And Justice and Podium fold to nearly the same footprint, both around 12.5 square feet, which is genuinely handy to know: if you were leaning toward Justice purely to save space in the corner, Podium is more available to you than you thought.
A walking desk, a walking pad and a full treadmill in one footprint that tucks against a wall. For anyone who thought a real treadmill would never fit.
Podium: runners and busy households
Podium is the one you buy when you want the machine to be the least interesting variable in your training. A 4.5 CHP commercial brushless motor, 14 MPH, incline to 18 percent, a 22 by 60 inch deck on CloudStride MAX cushioning, and a 350 lb capacity. Those are gym floor numbers in a machine that lives in your house.
Which Aviron treadmill is best for running?
Podium, and two numbers tell you why. The first is deck length. Sixty inches is the widely accepted minimum for a full adult running stride, and Podium gives you exactly that, 22 inches across, so you can relax into your natural stride instead of managing it. The second is the motor rating. Look for CHP, continuous horsepower, which is the power a motor sustains indefinitely, rather than a peak figure it can only touch briefly. Podium and Summit are both 4.5 CHP; Justice is 3.5. Comparing continuous ratings is the single fastest way to shop treadmills well, on our site or anyone else's.
Then comes the fun part. Podium folds, using the same one-handed SafeLift mechanism as Justice, which machines at this tier almost never do. And it takes the WalkDesk. So the runner in the house gets a serious treadmill, and everyone else gets a walking desk and a games console, on the same machine, on one membership with unlimited profiles. Households tend to find that this becomes the most-used object in the building. More on sharing one machine in can one treadmill work for an entire family.
Commercial-grade running specs that fold away and take a walking desk. Enough machine for the runner, enough fun for everybody else.
Summit: climbing and hiking training
Most treadmills stop at 15 percent. Summit goes to 42, and then it goes downhill to minus 6. If you love incline, that sentence is probably all you needed.
Grade is the most efficient intensity there is. Published research on incline walking measured metabolic cost rising roughly 52 percent at a 5 percent grade, and about 113 percent at 10 percent, compared with walking on the flat. You do not need to run faster to work harder. You just go up. It is why 12-3-30 became a phenomenon, and Summit has plenty of headroom above it.
Everything about it is built for the climb. Hiking handles carry incline and speed keys plus heart rate sensors, so your hands stay where you want them on a steep grade. An LED strip lights the belt. The deck is 22 by 61 inches, the largest in the lineup, on Max CloudStride cushioning with extra-large shock absorbers. Pick a route on Aviron World and go somewhere.
Is a StairMaster better than an incline treadmill?
For pure vertical a stair climber is excellent, and plenty of mountaineers love theirs. What a steep treadmill adds is a walking gait that matches how you actually move on a trail, speed as well as grade, and a descent to train. Downhill matters more than people expect: research by Kuster and colleagues measured patellofemoral compressive force in downhill walking at roughly three to four times level walking, which is exactly what your quads meet on the way back to the car. Train both directions and the mountain feels shorter.
The steepest incline range in the category, hiking handles, and the biggest deck in the lineup. Bring the mountain indoors any day of the year.
What every Aviron treadmill comes with
This is the part that makes the hardware decision feel low stakes, because the best thing about all three is identical. Aviron World is on every machine:
- Science-backed games you play by walking or running, where your pace is the controller
- Live racing head to head against real members, because other people are much more fun to chase than a personal best
- Scenic routes through real places when you want the session to feel like a trip
- Classes and coached programs for the days you want somebody else to decide
- Streaming, so Netflix, Hulu, YouTube and Disney+ are right there on the screen
- Pros vs Joes, Power Play intervals and structured training when you want a plan
More than 1,000 programs, plus over 300 Les Mills workouts, with new content added every quarter. One membership covers unlimited profiles, so everyone in the house gets their own progress, and it works across our rowers and bikes too.
The reason we build this way is simple: it works. Ninety two percent of Aviron members are still working out a year later, our verified buyers average 4.94 out of 5, and the single most repeated compliment across roughly 300 of those reviews, said in some form by more than forty different people, is that it does not feel like exercise. There is even clinical backing for the approach: randomized trials published in JAMA Internal Medicine in 2019 and Circulation in 2024 found that game mechanics measurably increased people's daily step counts, by roughly 920 and 868 steps a day in their strongest groups.
"Interactive and engaging. Workout is over seemingly before it even starts."
"63 minutes later I was drenched in sweat. Thought I'd hop on for 15 to 20 minutes. Started playing Rows to Riches. After a few minutes someone joined me and then a bit later someone else joined along. Not wanting to let the people that joined me down I just kept going."
"The only exercise machine I've actually used consistently."
Those reviews are from members on our rowers and the Victory treadmill, since Justice, Podium and Summit have only just arrived. The machines are brand new. The platform they run has years of happy members behind it.
And the machine is yours either way. Cancel the membership and your treadmill keeps working, with your metrics, your history, your profiles and your streaming apps all still there.
Still deciding? Three tiebreakers
- Justice or Podium? If anyone in the house will genuinely run, take Podium for the 60 inch deck and the bigger motor. If it is mostly walking, incline and the occasional jog, Justice does that job beautifully in a narrower frame for less.
- Podium or Summit? Ask whether you want incline as a feature or as the main event. Feature means Podium at 18 percent. Main event means Summit at 42.
- Want the walking desk? Then it is Justice or Podium, since Summit is not desk compatible. Everything else follows from there.
And if you are still torn, that is genuinely fine, because you get 30 days at home to decide. Full pricing by screen size is in the launch announcement.
Frequently asked questions
What incline should I walk at on a treadmill?
Start between 3 and 6 percent at a pace you can hold a conversation at, and let the hill do the work rather than the speed. Published research found a 5 percent grade lifts metabolic cost by around 52 percent over walking flat, so even a gentle incline is a real session. The popular 12-3-30 protocol sits at 12 percent, 3 MPH, 30 minutes, and makes a great goal to build toward. All three Aviron treadmills reach 12 percent comfortably.
How long does a treadmill deck need to be for running?
Sixty inches is the widely accepted minimum for a full adult running stride, and it matters most for taller runners on longer efforts. Podium is 60 inches and Summit 61, so both are set up for running. Justice is 59, which is great for walking and jogging.
What does CHP mean on a treadmill?
CHP is continuous horsepower, the output a motor sustains indefinitely, as opposed to a peak figure it can only reach briefly. It is the more meaningful number when you compare machines, which is why we quote it. Justice is 3.5 CHP, and Podium and Summit are both 4.5 CHP commercial brushless.
Which Aviron treadmill is best if I mostly walk?
Justice, usually. It walks and jogs happily, folds away between sessions, and takes the WalkDesk if you want to walk while you work. Choose Summit instead if your walking is specifically incline walking, hiking prep or 12-3-30, because that is where the extra grade really pays off.
Do I need the steepest incline?
Only if you will use it, and we would rather point you to the right machine. Summit's 42 percent is a joy if you climb, train for terrain or have outgrown 15 percent. If you will happily live between 0 and 15, Podium's 18 percent already goes beyond what most treadmills offer.
