I Think I Lost Hair Because of Exercise

I have lost most of my hair because of exercise. I stopped exercise for couple of months & retrieved almost 30% of my hair loss. but the problem is I am a fitness professional and cant live without a workout but as soon as I start my workout which includes weight training I start losing my hair. can anybody help me? whats the relation between exercise & hair fall? if you see, most of the body builders are bald but why?????

There is no connection to exercise and hair loss unless you have a telogen effluvium that is caused by stress. Are you stressed when you exercise with your clients? Even this scenario is far fetched. I would have to examine you and take a careful history to understand your problem better. I would be venturing a guess without knowing more.
