Interval training is far more superior to boosting your metabolism than it is to do steady state aerobic training. Steady state aerobic does not increase your metabolism at all. It is true that you are burning calories while you are actually performing the aerobics. However, once you are done with your session, your metabolism returns to normal.
However, interval training (consisting of moderate to high intensity cardio) will burn more calories per minute, and will elevate your metabolism for hours and hours. The right amount of resistance training combined with an intense interval training session can keep your metabolism up for at least 24 hours and in some cases, up to 42 hours. Imagine what that can do to your body if you are burning high amounts of fat all day and all night long (even when you are sleeping).
is it true, i need some feed back from the experts
