You are a Fat Burnin' Machine
Now that we are into the final stretches of the Tour de France, do you wonder what those world-class athletes have that make their bodies respond to the rigors of a race like that? I mean, 21 stages over 3,300 kilimoeters? (That's 2086 miles, friends!)
And we're not talking doping here!
It's fat burn.
They have trained their bodies to rely on fat as the primary source of fuel.
Here's some science for you:
First, you eat...
Most of us don't have trouble with this part. But now that you are working out and an athlete, what, how and how often you eat is super important.... but that's another newsletter.
Next, you break it down...
Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach. When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called
Then, you convert...
This is an important step. Your muscles can't use Glucose, so it converts it into
. It's really complicated and really cool, and if you want to get even more science-y look up:
- Adenosine Triphosphate (ATP) (C10H16N5O13P3)
- Adenosine Diphosphate (ADP) (C10H15N5O10P2)
- Krebs Cycle
But enough of that!
This little chart shows that the body stores Glycogen in 4 areas:
- Liver ~ 300 Calories
- Muscle ~ 2000-4000 Calories
- Blood ~ 40 Calories
- Fat ~ a whopping 100,000 Calories!!!
So you can see why we are so keen on training our bodies to engage and use fat to burn energy!
Finally, you use it...
Whether it's running, walking, breathing or doing a killer 614Fitness workout, you need your muscles to move. Inside every muscle is a little Everready battery called the
Mitichondia that uses Glycogen to make those muscles fire. You can only store a limited number of calories in your muscle, so you must call on other sources, mostly fat, to provide the needed energy (Glycogen). Long, sustained work in zone 2 is one of the best ways to train your body to become a fat-burning machine!
And That's Why We Do Zone Training
Inside every muscle cell is a little Energizer Bunny called the Mitochondria
