Curved Treadmills

A curved treadmill has a concave slat deck on bearings. Running on the front of the curve pushes the belt backward and the belt speed follows your stride; move toward the rear and it slows and stops. There is no motor, no speed button, no power cord and nothing to subscribe to. Resistance, where offered, is a magnetic or friction brake on the belt that makes each stride harder, which is what the sled push mode on the Air Runner Elite Pro uses.

Because you supply all the power, the same pace feels harder than on a motorized belt, which is why gyms use curved treadmills for sprint intervals and conditioning rather than long steady runs. The "manual treadmill" most people search for is this format; flat manual treadmills are a separate, lighter category we do not sell.

The two MedEq listings state no manufacturer warranty; the two SFE units carry 1 year. Ask us before ordering a MedEq unit if warranty cover matters to you.

• Resistance. 7 levels on the Air Runner Pro, multiple adjustable levels plus sled push on the Elite Pro, adjustable on the R1000. A brake you can set is what turns a sprint deck into a conditioning tool.
• Deck and slats. All four use a curved slat belt; running surface dimensions are not yet published on these listings, so ask us if you are tall or run with a long stride.
• Frame. Steel on the SFE units, solid wood on the R2000.
• Footprint and weight. Curved treadmills are long and heavy and do not fold; dimensions and unit weights for these four are available from our team. Plan on two people to move one.
• Monitor. The SFE units have a battery or self-powered performance monitor with speed, distance and time; none has a touchscreen or a subscription.
• Warranty. 1 year on the SFE units; none stated on the MedEq units.

• Garage gym, sprints and conditioning: the Air Runner Elite Pro, for the sled push mode.
• Lowest price: the Air Runner Pro, when it is back in stock.
• Studio where the equipment is on show: the R2000 solid wood.
• Steady-state running, incline programs or a screen: a motorized unit from the treadmills page instead.

Stock on these machines moves; a listing marked in stock ships within about 3 business days, a listing you can add to cart without an in-stock badge is on backorder from the supplier (ask us for the current lead time before you order), and a sold-out listing can be reserved by email.

Curved treadmills ship by freight on a pallet, mostly assembled. No outlet is needed; place it on a level floor with clear space behind it.
