for most people including children and teens the challenge is to get enough physical activity. however excessive exercise and overtraining often coupled with restrictive eating can be a problem especially for some female athletes and dancers as well as girls who become obsessive about weight loss. overtraining like eating disorders can result in decreased estrogen and eventually lead to thin bones that break easily. years ago it was not unusual for coaches and trainers to encourage athletes to be as thin as possible for many sports including dancing gymnastics figure skating running and diving. fortunately many coaches now realize that being too thin is unhealthy and can negatively affect performance as well as lifelong health.
can i get too much exercise?
