6 Pack Abs - Competing Theories
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.
Exercises that build muscle tissue speed-up the body's metabolism, making it easier to get rid of stored fat. Total body aerobic exercises that keep the heart rate at raised levels burn calories and reduce body fat effectively. There is some debate however as to what intensity levels the heart rate should be at.
There's low intensity cardio exercise and those done at high intensity (around 90% of the maximum heart rate). The low-intensity theory is has more followers because although workout sessions are longer, they're relatively easier and so beginners, the aged and obese can execute them.
Low intensity cardio exercises have also been discovered to burn caloric energy from fat stores as opposed to high intensity cardiovascular workouts that keep the heart at 90% of the maximum. The latter burns more calories obviously, but some of it comes from glycogen already.
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.
On the other hand, high intensity exercises burn loads of calories even if done for just 10-20 minutes. This means considerably less time can be spent in the gym and proponents say the lost glycogen can just be replaced anyway by eating carbo-rich food after working out.
High intensity folks also say hard cardio exercise causes muscle development because it works the whole body hard. In addition, intense workouts kick-up the body's metabolic rate hours after leaving the gym. The more calories spent throughout the day, more fat loss and faster 6 pack abs.
Another disadvantage of low-intensity exercises is it takes 10 minutes before the heart rate goes high enough to be able to start burning calories. It's clear that choosing between the two cardio 'schools of thought' depends on how much time a person can allot to exercising each day to get 6 pack abs and how developed his cardiovascular system is. - 17268
