We’ve said it before: Unless you’re blessed with land, or a giant warehouse, most of us are rocking a one-or-two car garage and simply trying to make it our home gym.

Space it at an all-time premium.

And hybrid training exposed how much dead space is sitting in most home gyms. For HYROX, you need enough to do 8 stations. And to do it right, you need a treadmill for tempo work and a sled lane for pushes and drags. Most people have room for one, not both.

REP thinks it solved that (and we believe it) with the Strive™ Curved Treadmill.

It’s a motorless, self-powered curved runner that converts into a resistance sled with a lever pull. There is no motor, and no cord, and from what we can tell, no compromise between the two. It looks pretty damn genius.

There are eight levels of magnetic flywheel resistance simulating up to 550 lbs, a legitimate sled replacement bolted onto a treadmill. Move the legs as if you’re pushing a sled, all while staying in motion on the curved runner. Our mind was freaking blown and it remind us of those BowFlex dumbbells that the unlimited weight variations. Just so damn smart.

How it Works

Curved treadmills already have a built-in advantage for hybrid athletes. No motor means you control the pace entirely, which builds the kind of midfoot mechanics and power output that a belt-driven machine can mask. And REP’s version adds a magnetic flywheel behind the belt. Dial it up, and the belt loads like a sled — light enough to mimic an incline walk, heavy enough at the top of the range for a brutal push.

The key detail here is that a clutch fully disconnects the flywheel for Free Run mode and it matters because most resistance-capable treadmills we’ve tested still feel like they’re dragging dead weight even with resistance off. REP’s clutch removes it from the equation entirely, so your tempo work isn’t fighting residual drag.

You also get two deck angles: flat for endurance running, and a 3% grade for sprint and HIIT work, which is a level of adjustability curved treadmills haven’t offered before now.

REP’s New Realm from Strength to Well Rounded

The frame is beast at 418 lbs, rated to a 400-lb user weight, with a 17.6-inch glass-filled nylon slat belt for traction. Ergonomic 32mm handles give you low and shoulder-height grip positions for both running form and sled pushing and a second, foot-level console tracks your sled work without breaking form to check the main display, while the primary 5″x8″ console handles distance, speed, power, and calories with Bluetooth/ANT+ connectivity for heart rate straps and FTMS apps.

And because it needs zero electricity to run, you can wheel it anywhere.

Our Thoughts

REP built its name and reputation on racks and barbells before expanding into cardio with the Strive™ Air Bike earlier this year.

This is the second product in that line, and it’s a direct answer to a problem hybrid athletes have with working out at home. HYROX-style training demands both engine work and load work, and most home setups force you to choose which one gets the square footage and most times the cheap price tag.

This is not cheap, but you may be able to justify it. For $3,799.99 (U.S.) / £3,499.99 (U.K.), you are getting two hugely important hybrid workouts in the form factor of a 418 lb monster that is shorter than 7 feet.

A treadmill that goes from free-run speed work to a near-550-lb sled push in the time it takes to flip a lever is the first piece of cardio equipment we’ve seen built specifically around the future of training, not the other way around.
