10 Things Your Fitness Club Won't Tell You

1. "If you're still here in April, it'll be a miracle."

The fitness craze is going gangbusters, with gym attendance up 23% since 2001, to 41.3 million, according to the International Health, Racquet and Sportsclub Association (IHRSA). And most new recruits sign up in January — the busiest month for fitness clubs. That's when well-intentioned souls trying to stick to their New Year's resolutions flood their local gyms, often resulting in long lines at the treadmill, overtaxed gym staff and towel shortages in the locker room. But it won't be long before the throngs thin; most resolution makers trip up in the first 90 days, says Alan Marlatt, director of the Addictive Behaviors Research Center at the University of Washington. And indeed, that's what clubs expect. "They bet on it," says Meg Jordan, editor of American Fitness, adding that most gyms count on a 20 to 30% dropout rate.

2. "Don't touch anything — this place is crawling with bacteria."

About 80% of all infectious disease is transmitted by both direct and indirect contact, says Philip Tierno, director of clinical microbiology at New York University Medical Center and the author of "The Secret Life of Germs." That makes the gym, with its sweaty bodies in close proximity, a highly conducive environment for catching everything from athlete's foot to the flu.

3. "We're not equipped to handle health emergencies."

Almost one-third of sudden cardiac arrests outside of homes and hospitals occur in fitness clubs or sports facilities, says Mary Fran Hazinski, a registered nurse and senior science editor at the American Heart Association. Yet most health clubs aren't fully prepared for such crises. That was the case at a 24 Hour Fitness in California, where Nick Pombra, 43, collapsed after running on a treadmill in July 2004. Gym staff tried CPR, but by the time paramedics arrived, it was too late, says Mike Danko, a lawyer for Pombra's family. 24 Hour declined to comment.

4. "Our trainers don't know what they're doing."

If you work out at a gym, chances are an on-site personal trainer will try to sell you his or her expertise. And with their Colgate smiles and buff bodies, they must be able to teach you a thing or two about getting into shape, right? Not necessarily. Trainers need no standard certification, and the credentials some flash require only a quick online course or a fee, says Neal Pire, a fitness-industry consultant and former trainer.

5. "We won't let you quit."

If you think giving up the Ben & Jerry's is tough, try quitting your gym. Trouble canceling membership is one of the top complaints against fitness clubs logged with the Better Business Bureau and states' attorneys general offices. Before Chris Hinkle and his wife moved to North Carolina, they met with the manager at their Gold's Gym in Austin to cancel their prepaid membership. They were told a refund check would be in the mail. That was March. After months of unreturned calls, Hinkle contacted the BBB, which also got no answer from Gold's and gave it an unsatisfactory rating. "I was an ecstatic booster of Gold's," Hinkle says. "Now I tell people to never go there." A Gold's spokesperson says the club sends a refund in such cases once it receives proof of a move — documentation Hinkle says the Austin manager didn't ask for in March.
