Top Workout Tip #1: Workout Harder NOT Longer!
You now know that cardiovascular exercise is an important part of your weight loss program. The problem is you may have been told the wrong way to perform it.
The old rule of thumb for fat loss was you needed to be able to talk comfortably while exercising. The reasoning was based on how fat is released for energy in the body. Fat is released and used for energy during aerobic respiration.
Without getting too technical, exercise that lasts longer will use aerobic respiration while exercise that is done in shorter durations like sprinting or weight lifting uses anaerobic respiration.
It all has to do with availability of oxygen for energy production. Since fat is released during anaerobic respiration researchers thought that exercise should be completed in lower intensities for longer durations.
That is why they had the “talk” test. If you couldn’t talk while exercising it was thought you were working too hard to effectively release and burn fat.
Well scientifically the theory looked great on paper, but you have to look at the big picture. The fact that fat is released during aerobic respiration is not enough. It all comes down to the total amount of energy used during and after exercise.
Working at a higher intensity will not only burn more calories during exercise but will also help burn more calories after you’re done. The good news is you don’t have to work out for hours. A half hour at a higher intensity will actually be more effective than an hour at a lower intensity.
