Finding a workout is easy. Just pick up a fitness magazine, follow a video, read umpteen-and-a-half gym advertisements.

Voila! You’re on the pathway to a dream physique.

In theory, at least. In real life, not everyone can afford a gym membership or a set of dumbbells. Or there’s a problem with getting to the gym, during the day or especially at night.

Not to fret. There are ways to get fit and to stay fit. All you need is some desire, a bit of determination, a doorknob and a chair.

“You don’t need fancy things or a gym,” says Elizabeth Lindberg, owner of Studio 6 Fitness in Dallas. “We’re known for a very, very expensive machine here, but we also do barre. When you go to a barre studio, it’s fun in a group fitness environment. But the moves that make it so popular, you can do on the back of a chair or a bar in your house or the kitchen counter.”

We asked Lindberg and John Mariotti from another Dallas-area facility — CrossFit Odyssey and Odyssey Martial Arts studio — to devise workouts that just about anyone can do. (If you haven’t worked out in a while or have health issues, be sure to consult your doctor first.)

“It doesn’t have to be a lot,” Lindberg says. “You can get a benefit in just 30 minutes.”

Mariotti suggests starting small to set yourself up for success: Two workouts the first week, increased to three for a month or more. Then you can add more or increase the intensity.
