It’s right around the corner: swimsuit season.

That means it’s the time of year people start pondering their waistlines and thighs and begin imagining how they’ll look in a bathing suit, lounging pool side.

Not happy with what they see, some people throw themselves into an exercise frenzy trying to drop some pounds and trim up those tummies. It’s already happening.

“Business is picking up,” said Christie Curtis, day manager of Curves for Women, 2104 W. 25th St. “I have a feeling it has to do with summer, sunglasses and bathing suits.”

If you’re among those hoping to whip up a slimmer summer in a hurry, there’s bad news: You’re already too late.

But there’s good news, too, local fitness experts say.

It’s never too late to embark on a lifestyle change  rather than a crash program  that could result in a better physique and improved health year round.

Rick Sells, owner of the Lawrence Athletic Club, 2108 W. 27th St. and 3201 Mesa Way, said a year-round fitness program is the smartest course.

“If you start right now, we’ll get you to look as good as you can for this summer  but next summer, you’re going to look fantastic,” he said.

So maybe you won’t get a gorgeous, new body in time for the first pool party. But you can adopt a measured, incremental approach to fitness that will lead you to the physique you’re seeking.

Marty Tuley, owner of Total Fitness Athletic Center, 2339 Iowa, tries to educate his club members to take a wider view of getting into shape and improving overall health.

So many people are solely focused on building six-pack abs or pumped-up pecs that they lose sight of the bigger picture, he said.

“People want to work on specific areas of their bodies. With men, it’s love handles. With women, it’s usually their outer thighs. The reality of it is, you can’t target a specific area and get results only in that area,” Tuley says.

Lasting results come from an exercise program that includes cardio training, resistance training and proper nutrition. Too many people focus on just one of these aspects  typically, severe dieting.

But it takes a sensible diet, good mix of aerobic training and resistance training to achieve lasting results.
