Hello,

The answer is option B "The positive impact of exercise over a period of time on muscles, metabolism, heart health, and blood pressure".

Reason:

Fitness effect is how a person positivity was effected by working out for a short period of time. For example runs on a mill records to amount of calories you burn. Its not option A because the FITT principles are about mostly your goals about losing weight. Its not option C because thats taking your pulse and also the process of taking your blood pressure. Its also not option D because that would be FITT its your endurance through a intense exercise program. Therefore the answer is option B.

If you need anymore help feel free to ask me!

Hope this helps!
