TV HUNK DISCOVERED: STEVE PFIESTER

Here’s one good reason for me to strap on those sneakers and take a walk: Fat March’s Steve Pfiester. He’s the reality show’s hunky male trainer, and I’m pretty certain his biceps are bigger than my thighs. Steve, 36, owns Longevity Fitness club and spa for women in Vero Beach, Fla. With 13 years in of experience in kickboxing and personal training, Steve whips his clientele -- which includes fitness competitors to soccer moms –- into the best shape of their lives. Unfortunately for the rest of us (okay, me!), Steve’s already taken. His wife of 13 years, Bonnie, is also employed the workout biz. “He doesn’t know he’s cute,” she says. “He’s very real. He wouldn’t know how to put it on if he tried.” Buffed and humble too? I need to start hanging out more at the gym! Fat March airs tonight at 9 p.m. on ABC.
