Consumer Reports evaluates exercise range because you want a machine to be able to keep up with you as your fitness level increases. Testers also look at how easy the machines are to use.
The recommended $3,700 Precor TRM-243 treadmill has a screen that looks like a tablet. And the buttons on the top-performing, $2,300 Sole TT8 are easy to read and push while you're on the move.
For a lot less, consider the $1,500 NordicTrack Commercial 1750. While it did show a little wear in Consumer Reports' durability tests, it offers excellent exercise range. Plus it folds up so it'll save space, too.
As for ellipticals, Consumer Reports says ergonomics are key. A good machine like the Schwinn 470 smooths out the pedaling. It also offers 29 different pre-set workouts and is a Consumer Reports Best Buy at $800.
Whatever exercise equipment you buy, Consumer Reports says it's a good idea to bring your sneakers to the store to try it out and make sure the machine is comfortable for your body.
