36-24-36 As Sir Mix A Lot would claim, "Yeah, baby ... when it comes to females, Cosmo ain't got nothin' to do with my selection. 36-24-36? Ha ha, only if she's 5'3"!
The C.S.C.S. - Certified Strength and Conditioning Specialist. This is the certificartion given by the National Strength Coaches Association (NSCA). Requires a 4 year college degree; this is the certification most of the university and pro sports teams strength coaches have. The rest are something like 40 hour courses, just take the course and get "certified." This is the kind of thing most of the idiot trainers in health clubs like Bally's have. A halfway decent course is offered by the American College of Sports Medicine (ACSM). The rest amount to little more than correspondence courses anyone can (and does, obviously) take.
trader56 is spot on. My sister is a "Certified Trainer, ACSM". She carefully researched the major certification choices a couple of years ago and that's the one she went for. She's also a "Group Fitness Leader, ACE" (American Council on Exercise), looking at her business card. She says that's just a useful thing for getting jobs teaching aerobics classes.
