Aside from how many calories are burned exercising, another way to approach fat loss is through upgrading your fitness level. Research from the University of Southern Denmark has shown that our fat-burning engine increases in power as we become more fit.
In fact, researchers from the University of Guelph found that with just seven sessions of high-intensity interval training over two weeks, fat burning capacity increased by 30 percent.
High intensity interval training has also been shown to be more effective at boosting your fitness level more than moderate intensity training.
Steady-state cardio is still great exercise, especially on decreased training load days or for endurance events. Just make sure to include some high intensity interval training (HIIT) as a means to increase your fitness level.
As a result, you will end up burning more fat during your steady-state cardio, since your aerobic threshold will have increased from the interval sessions.
