Brands, explained

NordicTrack makes good treadmills and sells them with a subscription, so decide on iFIT before you fall for a screen.

ProForm is NordicTrack's cheaper sibling, made by the same company with the same iFIT subscription attached.

Sole puts its money into the parts that last: steel frames, thick decks, motors with a lifetime warranty and consoles you won't need to replace.

Horizon is the home brand of Johnson Health Tech, the company behind Matrix gym equipment, and its treadmills draw on the same supply chain for rollers, decks and motor controllers.

Every current Bowflex treadmill is rated to 400 lb and carries a 15-year frame and motor warranty, which is rare at these prices.

WalkingPad is the brand that invented the fold-in-half walking pad, and it uses brushless motors across the lineup.
