The New Work­out High

It’s no sur­prise tread­mill classes are pro­lif­er­at­ing. As HIIT reigns, these ma­chines are get­ting new­found cred as real body chang­ers.

How to reach it ev­ery time


magic that other car­dio equip­ment can’t quite match. Com­pared with the usual sus­pects (row­ers, Spin bikes, el­lip­ti­cals, stair climbers, cross-coun­try ski ma­chines), tread­mills can help you burn more calo­ries at ev­ery in­ten­sity. “Also, run­ning on a tread­mill pro­motes dy­namic bal­ance, some­thing you don’t get on seated equip­ment like a bike or a rower,” says Christi Brewer, Ph.D., an as­sis­tant pro­fes­sor of exercise sci­ence at East­ern Wash­ing­ton Univer­sity. A new study by Brewer showed that a tread­mill run can even out­burn a high-in­ten­sity weight cir­cuit. At the same heart rate, ex­er­cis­ers do­ing a steady 20minute tread­mill run burned 37 per­cent more calo­ries (206) than do­ing

20 min­utes of cir­cuit train­ing with weights (fast-paced reps for 30 sec­onds and no rest be­tween sets), even though they rated circuits much higher in per­ceived ex­er­tion. “While cir­cuit train­ing does get your heart rate within an aer­o­bic train­ing zone and feels more stren­u­ous than tread­mill run­ning, it does not burn as many calo­ries at the same heart rate,” Brewer says.
