6 Pack Abs - Different Opinions

By Dan Solaris

Time and again, expert studies have shown that total body cardiovascular exercises are most effective in eliminating excess body fat. There's no way to bring out the striations and contours of the abdominal muscles to show a 6 pack unless the belly fat is reduced enough.

Though there's little contest about the effectiveness of combining resistance training and aerobic exercises for developing a lean, shredded midsection, there is some debate as to which type of cardio exercises to do. Building muscle raises the metabolism and cardio exercise burn calories from body fat.

Cardiovascular exercises can be done at low intensity and high intensity. The latter is more popular as a method of losing fat and getting 6 pack abs because first, it's easier to do. The physical effort in doing low-intensity cardio exercises can actually be done by novice exercisers and people that are extremely overweight.

Another aspect the low-intensity cardio theory has going for it is that it's a proven fact that exercises done at low-moderate intensity over an extended period targets body fat as the only source of calories used up. Exercising at intense levels actually cause the body to use up carbohydrates as well as fat for energy also.

The body absorbs carbohydrates from the food we eat and stores it in muscle tissue as glycogen. Supporters of the low-intensity theory say working-out too intensely can cause the loss of muscle tissue because some glycogen is used for energy when doing hard workouts.

Doing cardiovascular at high intensity however burns way more calories in less time than cardio exercise at low intensities. An hour's worth of calories burned doing the latter can be eliminated in just 10-20 minutes intense exercise. Some also argue that the lost carbohydrates can be replenished by eating the right post-workout food.

Some experts argue that although they're more difficult to do, high intensity exercises in fact build more muscle tissue because of the hard effort. They also kick the metabolism up to high levels and keep it going hours after a person has stopped working-out.

Low-intensity exercises may not be for people that are on a tight schedule because aside from hour-long sessions, it takes a full 10 minutes for the fat-burning effect to kick-in after beginning the workout. Intense cardio exercises, although more potent in the calorie-burn department may not be for everyone because of its difficulty. - 16887
