Comparing this to humans would be like a growing fetus.
Once stars have reached equilibrium fusion will stop after a while due to the lack of hydrogen, and the core temperature will drop. Gas can't resist gravity anymore so the star begins to contract. As the core shrinks the atoms become tightly packed and they start gaining heat. The core keeps gaining heat until it can begin nuclear fusion again. This cycle continues until all of the hydrogen is gone.
