Boost your fitness level by increasing the intensity of your workouts! Pushing yourself out of your comfort zone triggers the release of biochemicals in the body that result in stronger muscles and increased fat burning.
Intense exercise triggers changes in the body and muscles that moderate physical activity doesn't match, according to a new study by the Scripps Research Institute in Florida. A class of biochemicals called catecholamines, such as adrenaline, are released only when the intensity of the exercise pushes you out of your comfort zone. The release of these catecholamines sets off a sequence of events in the body that result in tighter, stronger muscles and more efficient fat burning.
Continually push yourself to gain the greatest benefits from your workouts!
