During exercise, the muscles get stronger and the bone mass gets larger.
During exercise muscle cells use oxygen.
the muscles produce lactic acid which then relieves the muscles but it results in muscle cramps

The pectoralis major muscle is primarily targeted during a bench press exercise.
Yes. Strenuous exercise can kill the muscle fibers. Such muscle fibers are replaced by fibrous tissue.
You will see muscle development after exercise, not during.

You lose muscle tone and general physical good health.
