Exercise trends tend to change frequently, in the last eight years we have gone from low-intensity fat burning classes to high intensity exercise. At the end of the day it leaves the average exercise enthusiast confused, not knowing the best way to spend their limited amount of “exercise time”.
In order to bring clarity to my clients training session an explanation of the science behind these theories is needed. Low heart rate training (50- 60 percent of max heart rate) is unlikely to burn enough calories to achieve weight loss. On the opposite side of the spectrum performing high intensity workout in a shorter period of time people burn mostly carbohydrates. The normal carbohydrate intake for most Americans is 50- 55 percent of their diet, adding a hard high intensity work out trains your muscles to store carbohydrates. This increases glycogen storage capacity, desirable for competitive athletes, but not for us regular Joe’s. This added water weight is going to leave you very unhappy when you get on the scale.
The answer, focus on the middle, the key to burning fat more efficiently. The first thing you need to find out is where your middle is. I suggest have your personal trainer per form a sub maximal heart rate test, such as a 3-minute step test or a 1 mile walk, so that you are as accurate as possible. Even better if you happen to need an exercise stress test ask your cardiologist what your heart rate zones are. This way you have a better point of reference.
