Why take a treadmill class
The treadmill is a tried and true piece of fitness equipment. Here is why you should jump on with friends.

Move over, cycles! The tried-and-true treadmill is the latest darling of fitness class fans. You’ll see it everywhere, from dedicated running studios to boot camps. Why? Treadmills offer simplicity and flexibility—and they can kick your butt. Here are the five reasons you should consider using one with a group.
1) You can run at your own pace.
No more worrying about falling behind—or having to wait up—like when you run with your friends outside. On treadmills, you can each set your own speed and still run side by side.
2) You'll love low tech.
Mechanical treadmills are popping up across the country in gyms like the Canali Club in New York City. The draw? Woodway, which sells the motorless Curve machine, claims that you could zap up to 30 percent more calories on its treadmill than you would on a motorized belt.
