Glycogen is the preferred energy source for muscles for most exercise demands, however, it is not the only one and kerstin is disingenuous at best, to suggest otherwise
Depending on the type and intensity of exercise, muscle and liver glycogen can be rapidly depleted and there is an ongoing process of fat mobilization and lipid oxidation that also occurs concurrently, particularly, in long duration (lower intensity) activity.
