Insulin serves as a “key” to open your cells, to allow the glucose to enter -- and allow you to use the glucose for energy. Without insulin, there is no “key.” So, the sugar stays -- and builds up-- in the blood. The result: the body’s cells starve from the lack of glucose. And, if left untreated, the high level of “blood sugar” can damage eyes, kidneys, nerves, and the heart, and can also lead to coma and death.
Metabolic training (MT) is a hybrid of anaerobic strength training and aerobic cardio exercise. In a nutshell, effective MT training ignites your metabolism, allowing for a longer period of calorie burning. Essentially, your body's furnace is lit and on overdrive for up to 48 hours after the workout. The catch? The workout needs to be both intense and dense. Meaning you have to go all out and complete a high volume of work in a short period of time. An hour of weight training or a 30-minute jog around the park will not suffice.
