Enter the Burn Zone


Thermogenic supplements keep your body’s metabolism buzzing after a bout of cardio more than the effects of cardio alone, according to a study recently published in The Journal of Strength and Conditioning Research.

University of Oklahoma researchers gave 28 healthy (yet sedentary) participants a fat-burning supplement containing caffeine, capsaicin, niacin and black-pepper extract — or a placebo — after 30 minutes of rest. After taking it easy for 50 more minutes, everyone walked on a treadmill for an hour, followed by another 50 minutes of rest. The findings? Those who took the thermogenic formula burned more overall calories and experienced an increase in their aerobic capacity.

Take-home message: Although the study was on nontrained subjects, it gives further indication for the active set that fat-burning supplements can be a valuable aid in weight-loss efforts.
