I'm only 25 my knees and hips often click and cause discomfort in my workouts is there something i can do to prevent this? is this bad?

Not bad: Clicking of the knees and hip can be due to a variety of issues depending upon the body region. Most often, it is benign, though anyone experiencing discomfort should see a sports medicine physician. You might not be able to prevent the clicking, but a good exercise program balancing flexibility, strength and proper nutrition should help prevent injury.
