Have you ever wondered how long you should do aerobic exercise each day to achieve better health and wellness? You need not wonder anymore. First, you should determine, do you want to burn fat, or just achieve good cardiovascular fitness?

For most people it seems like the hardest thing in the world to accomplish. Yet people from all over the world spend thousands of dollars on the latest gimmicks for developing that elusive six-pack. Personal trainers can't keep up with the number of requests from newbies looking for quick fixes to fat loss and develop a ripped midsection.

People can be funny at times. They skip the stairs and take the elevator to the second floor - and then drop $3000 for a stepper machine to condition their thighs or burn bodyfat!

Bodybuilder or not, no one who's playing with a full deck wants to be carrying excess body fat. While weight training and dieting play major roles, to maximize fat loss you should also be doing some sort of cardiovascular training (more affectionately known as cardio) to compliment your bodybuilding workouts.

One of the most essential questions to ask when doing your cardio is am I training too intensely or not intensely enough? To help guide you in this regard the Target Heart Rate Zone (THRZ) can play an important role.
