New research finds males who participate in high contact sports such as football, soccer and rugby have a high risk of developing knee and hip osteoarthritis.
There was a doubled risk in soccer and a triple risk in ice hockey players.
The study in the American Journal of Sports Medicine looked at those who play professional or Olympic level sports.
Researchers hope the results speak to anyone who wants to start working out at intense levels. They say there are safer and better ways to exercise without risking joint injury.
