For starters, stop abusing the elevator. Unless you have a phobia of stairwells, take the stairs whenever you can and burn those extra calories. This also applies to any shopping excursions you might make to the mall. Try taking the stairs instead of the escalators so your body can benefit from the extra muscle use.

Whenever weather permits, walk to those places within a reasonable distance instead of driving. If you can walk a half-mile or so every once in a while, your body will become accustomed to greater use of muscles, tendons, ligaments and limbs. By walking to the post office, the convenience store, the coffee shop, etc., you can burn off calories and strengthen your body at the same time. By doing so on a regular basis, you can condition your body for a more regimented exercise schedule, should you choose to include one in your normal routine.

Consider getting into yoga, kickboxing or any group-oriented aerobic exercise. Join a YMCA and go swimming if it’s your thing. Commit yourself to following an exercise video program at least once a week, even if it is only for five minutes of an abdominal workout.

Find an exercise partner! Take your dog to the park and play outside a bit when winter’s bite isn’t so harsh.

Play outside! If enough snow covers the ground, get the gang together and dress warmly. Grab a football and some thermoses of steamy hot chocolate and play in the snow like old times.

Build your muscles by lifting weights. Try to set aside a small corner of your home or garage for a personal workout area. Lifting can be as intense or as simple as you make it, from actual bench presses to short reps with lightweight dumbbells.

Target a particular area on your body and work to improve it. Research online and in books about how you can tone or build up certain muscles properly.

Workout on your own time! Spend a minimum of five minutes a day, a couple days a week, doing sit-ups and crunches, pushups, pull-ups or other exercises that don’t require leaving the home.
