Extract:
HIIT — high-intensity interval training — is a combination of
high-octane bursts of intense exercise followed by low-intensity short
rest. According to the Academy of Sports Medicine, the benefits of HIIT
range from lowering cholesterol and improving blood pressure to lowering
body fat and maintaining muscle mass. A 20-minute workout such as
Musico’s can burn as many as 250 calories, and with HIIT’s ability to raise metabolism levels, you’ll burn fat long after you’ve taken off the gloves and gone back to checking your work emails.
