Explain why energy is stored in the form of glycogen in muscle cells

In the muscle it seems to be mainly used for energy purposes as metabolic fuel for glucolysis producing glucose 6-phosphate

glycogen plays a crucial role as a systemic and cellular energy source and also as an energy store.

hope this answer correct (^^)...

Glycogen is also stored in muscles and fat cells. In the muscle it seems to be mainly used for energy purposes as metabolic fuel for glucolysis producing glucose 6-phosphate. Thus, glycogen plays a crucial role as a systemic and cellular energy source and also as an energy store.
