Exercising is helpful and is actually necessary for a healthy body. However, recent trends in social media have made people feel less confident and thus attempt to lose weight in the worst ways. One of these ways is exercising too much, which can actually cause even more medical problems. For example, weakening of the muscles and bones are common side effects of over exercising. Though people may not associate being "addicted" to exercise as negative, it may still become a problem when not done in moderation.
