20 weeks endurance training vs. 15 weeks Interval training
Energy cost of endurance training = 28,661 calories. Interval Training = 13,614 calories (less than half)
The interval training group showed a NINE TIMES greater loss in subcutaneous fat than the endurance group (when corrected for energy cost)
Tremblay A, Simoneau JA, Bouchard C. Impact of exercise intensity on body fatness and skeletal muscle metabolism. Metabolism. 1994 Jul;43(7):814-8.
15 weeks of 20 mins per session interval training ( 3 x pw)
Vs 15 weeks of 40 mins of steady state exercise (3x pw)
Both groups burned the same total calories over the 15 weeks and ate the same diet.
Steady state group actually gained on average 1lb of fat.
Interval training group lost 5.5lbs of fat and increased lean mass.
Interval training group increased aerobic capacity more than steady state group.

If your goal is either to increase cardiovascular fitness or to reduce body fat then interval training should be you exercise of choice.
