Dont eat carbs after you exercise.

Treadmills and calories Exercising on a treadmill burned more calories than workouts on stairclimber, rowing machine, stationary bike or cross-country ski simulator, according to a study in The Journal of Medicine & Science in Sports & Exercise. Subjects exercised at fairly light, medium and hard intensities, and researchers measured oxygen uptake, heart rate and blood lactate during the final two minutes of each workout. Even at the easiest intensity, those on the treadmill burned the most calories. "Any of the machines could be used if the prime motivation for exercising is cardiovascular fitness," said researcher Niall A Moyna. "However, if burning calories is the main objective, the treadmill would be the exercise of choice for both men and women, followed closely by the skier."
