Lose belly fat fast and improve your health by doing strength training and high-intensity intervals. Compelling research shows that the BEST way to get rid of the belly fat is to train with hard but short bursts of exercise, a style that taps into the anaerobic energy system more than the aerobic.
There is overwhelming evidence that belly fat loss is best achieved when exercise is with a high, but varied intensity, and a relatively large volume. However, this does not mean you have to spend hours and hours a day killing yourself in the gym. Less than an hour a few days a week can produce dramatic fat loss if you do it right.
This article will tell you why you burn more fat when you favor anaerobic-style training and give you eight reasons to favor this style of training by lifting weights and doing sprints rather than spending hours on aerobic exercise.
#1: Burn More Belly Fat with Sprint Intervals
A large number of convincing studies show that high-intensity interval training is the best conditioning strategy for losing belly fat. In contrast, one research group that has conducted a number of experiments comparing aerobic and anaerobic training for belly fat loss write, “Disappointingly, aerobic exercise protocols have led to negligible fat loss.”
The reason anaerobic interval training works so much better is that it requires the body to adapt metabolically—your body is forced to burn fat to sustain the level of intensity being asked of it. It also elevates energy use for more than 24 hours post-workout, which has a dramatic effect on belly fat loss.
For example, a 2008 showed that a 6-week program increased the amount of fat burned during exercise by 12 percent and decreased the oxidation of carbohydrates—obviously, a favorable result for losing fat. More impressive, a 2007 study showed that in as little as 2 weeks, active women who performed interval training experienced a 36 percent increase in the use of fat for fuel during exercise.
Interval training is so effective for fat loss because it taps into different energy pathways than aerobic exercise. Simply, aerobic exercise tends to burn carbohydrates first and activate pathways that are degrading to muscle, whereas high-intensity exercise such as weight lifting and sprinting will burn a greater percentage of fat, enhance the body’s production of enzymes involved in fat breakdown, and activate pathways that lead to muscle development.
The other reason anaerobic intervals are superior for belly fat loss is that they increase excess post-exercise oxygen consumption (EPOC) a huge amount. A 2006 review showed that protocols that are more anaerobic in nature produce higher EPOC values than steady-state aerobic training because the trained muscle cells must rest restore physiological factors in the cells, which translates to a lot of energy expenditure.
