H.I.T means repetitive brief bouts of high-intensity exercise separated by short rest periods. This kind of training has been found to burn fat most effectively. It builds the highest aerobic capacity which means the ability for your body to transport and use oxygen is higher than any other form of training. “During aerobic activity, you repeatedly move large muscles in your arms, legs and hips. This maximizes the amount of oxygen in your blood. Your heart will beat faster, which increases blood flow to your muscles and back to your lungs,” according to the Mayo Clinic. Your muscles feed off of oxygen which in turn increase your stamina, strengthen your heart, and best of all, burns those cals as fast as you can sing “Hit me with your best shot!”
So “fire away” and try running sprints, doing jump squats or swimming laps.
