Do you remember what you took instead of health? I don’t have anyone to do this to since both my parents didn’t go to high school please help me

Can you explain it well?

People who utilizes the progression principle will ensure their exercise program increases in frequency, intensity, time, and type. the changes need to happen gradually in order to ensure they make gains in their fitness program. a person who doesn't utilize the progression principle can still gain health benefits from exercising, but will not continue to improve in cardiovascular fitness.
