exercising is “what does not kill you, makes you stronger”, but applied to your bones and muscles.
Exercise does damage your body. Normal exercise keeps this damage mild, so your body can heal it in a few days, and that healing process makes the healed parts stronger.
Overdoing the exercise can cause damage that can take weeks or months to heal, and while the healed part will be stornger, the rest of your body will be weaker from lack of exercise and diverting resources to healing the injury.
Also, lack of exercise means that your body will divert resources away from the unused muscles, so they will grow weaker.
So what you need to be healthy is moderate exercise.
