Nothing’s worse than getting caught cheating on your hairdresser. Except for being busted stepping out on your personal trainer.

Run away with your new fitness guru to Hi-Fi Personal Fitness, a private studio dedicated solely to personal training. Equipped with all the goods (free weights, cardio equipment, bands, balls, and mats), there’s no membership fee or monthly dues. All you pay is your trainer’s hourly rate; he in turn pays Hi-Fi a small fee. (Feel free to warm up before and cool down after your session.)

If you’re still flying solo in the weight room, give owners Drew and Gregg Shipp a call. They’ll match you up with one of Hi-Fi’s 40-plus trainers. And you won’t miss the luxuries of your mega-club (read: massage and waxing). The on-site aesthetician will rub you down and primp you silly.

Which might just make you unrecognizable the next time you and your old flame cross paths.

Hi-Fi Personal Fitness, 1030 West North Avenue, Suite 300, at Kingsbury Place (312-751–1224 or hififitness.com).
