Explanation:

Fitness is something we get with muscle building exercises and flexibility exercises. Fitness is the ability of our body organs to withstand the tasks of our daily lives, that is, those who have a good fitness feel less tired and uncomfortable doing physical activities, or some other activity that requires effort. Sedentary people, for example, will only have a good condition if they start to be more active and practice flexibility and muscle strengthening physical activities.

The physical activities and exercises put the body in motion, to get a better fitness, we need at least two types of physical exercises weekly, one focused on flexibility and another focused on muscle strengthening.
