Training to deplete glycogen stores

[Pseudonym]

I was watching a guy in the gym tonight do what seemed to be a form of HIIT circuit training. It went like this:

- Kettlebell cleans

- Chins

- 2 mins sprinting

- Repeat

He would run between each exercise, so I presume the whole thing was timed. It was sort of HIIT without the rests.

It looked like a good way to deplete the glycogen stores from as many muscles as possible. Which would make it an effective method for fat loss.

Or so I imagine. Has anyone tried this? Can anyone confirm my theory?

Would be good for fat loss in terms of burning off glycogen stores in the liver and burning fat for energy but glycogen stored in the muscles can only be used locally (by that muscle) and cannot be passed into the blood stream as muscle tissue lacks the enzyme glucose-6-phosphate required to do this. So in theory muscle glycogen cannot be used to by rest of the body well so would not interfere with the rest of the bodys use of fat for energy.

I think the general consensus about full body workouts for fat loss is that your heart rate is going to be higher and your going to be burning more calories

Just my 2 cents anyway

Not sure I follow you there, Ninja. Run that past me again?

My thinking was that this style of workout would deplete glycogen in multiple muscle groups, rather than just one (which would be the case with a standard one-body-part workout). With more glycogen depletion throughout the muscles, the liver is forced to release more of its glycogen to replace those levels. That in turn sees more fat being used to top up the liver. Is my very rudimentary layman's understanding not how it works?
