fat-loss zone, cardio zone rubbish part 2
Fallacy of the "Fat-Loss Zone"
Without delving too deeply into a physiology lesson, the idea is as follows...keeping aerobic intensity moderate will give the body enough time to convert fat cells into free fatty acids, which are then used as muscle energy.
To refresh your memory, one moves from the "Fat-Loss Zone" to the "Cardio Zone" by increasing intensity. This will decrease the % of fat usage by increasing the % of carb (glucose) usage.
So, we can conclude that the basis of the "Fat-Loss Zone" is to keep the % of energy specifically coming from stored fat, right?
If this is the case, then we can also conclude that sitting on the couch and doing nothing is even better because it yields a higher % of fat-burning (your body has all the time in the world to convert fat to energy).
Hmmm, maybe this exercise stuff is bogus after all?
Obviously I jest, but my point is this...it's not about the % of fat vs. % of glucose, RATHER, it's the calories burned during the session AND the metabolic impact long after the session is complete. This is when fat loss is truly maximized!
I give credit to expert trainers such as Alwyn Cosgrove and John Berardi, who present such great examples from real-world experience. Training is all about energy expenditure to GET your body lean and clean nutrition to KEEP your body lean!
Looks like part 3 will include my promised solutions to effective cardio training. I'll simply leave you with this thought...compare the physique of a world-class track star to that of a world-class long-distance runner.
Make it a great day!
