There's always plenty of calories available in the form of glucose or glycogen.
So metabolic flexibility describes the ability to extract energy from the fat stored on your body, the fat on your plate of food, the glucose in your bloodstream, the glycogen in your muscles, the carbohydrates that are on your plate of food, the ketones that your liver makes in the absence of glucose.
And once you develop the state of flexibility, a whole world of empowerment opens up where you're not tethered to appetite and cravings and cravings
hunger all the time.
Your day isn't dictated by when mealtimes are.
You have all the energy you want all the time for the most part.
And one of the side effects of that is because you're continually burning off your own stored body fat, you tend to have low body fat, which a lot of people think is a good thing.
And I'm one of them.
Yeah.
We're both one of them.
So back to how did I get to where I am today?
It's a combination of some initially starting with aerobic athletics, cardio, they called it in those days.
They still call it cardio.
And transitioned over to weightlifting and speed and strength, which I think was probably the right way to do it.
And then recently have combined the two of them.
So I was...
you know, telling your husband, I ride a fat bike on the beach, a fat tire bike on the sand in Miami.
Do that at least once a week, sometimes twice a week.
It's a brutal workout, but it's a lot of fun.
Yeah.
