A) Fitness is the ability to endure daily tasks without getting tired too much.
it doesnt matter whether it is trying to catch a bus, running after your energetic child, or simply going from point A through point B to point C.
Keeping your body healthy is balancing your diet, exercising daily, having a healthy sleeping pattern, and managing a stressful event.
it seems hard.. but once it becomes a routine, it's no problem!
