Question

A weightlifter who practices five hours a day observes that his muscles have gotten larger. he tells you that his muscle cells are dividing and consequently making him stronger, so he can lift more weight. is his explanation correct? why or why not? how would you explain muscle structure to the weightlifter?

Answer 1

His explanation is wrong.

When a person does bodybuilding, the number of his muscle cells remains the same compared to a person who does bodybuilding, the difference is that his cells will become bigger, and that is why the muscles take on an appearance bigger when a person does weightlifting.
