You already know that exercise is good for you. Exercise helps to manage stress, get your weight under control, and lower your risks of killer diseases including heart disease and diabetes. But fitting exercise into a busy day on the road can be quite a challenge. What's your excuse?

• No time?

  Research has demonstrated that three 10 minute chunks are just as effective as a 30 minute workout. Do 10 minutes of exercise while you watch the news in the morning. When you need to run an errand during the day, slip on your sneakers and step out at a brisk pace. In the evenings, take a walk in the convention area.

• Too much to do?

  Sometimes it's hard to think at your desk. Take a walk to brainstorm or practice your upcoming speech.

• No workout room in the hotel or bad equipment?

  Check with the concierge for another workout facility in town, local walking course, or do Dr. Jo's Hotel Room Workout. This is a 30 minute full-body workout that alternates between aerobic activity (dancing, running or marching in place, jumping rope, etc.) and sets of strengthening exercises using exercise resistance tubes.

• Bad weather outside?

  Walk the hotel halls, the local mall, or do a "stair stepper" routine on a safe stair well. If the indoor pool isn't big enough to swim laps, tread water for a tough, full-body workout.

• Exhausted?

  Most of our fatigue is due to mental stress that zaps our energy - and exercise is just what we need to recharge our body and mind.

• Exercise too stressful?

  You may be working out too hard. Tone down the length of the workout or the intensity.

• Bored?

  Pair your workout with TV or music or with a book, newspaper, or magazine. Instead of going to lunch or having a business discussion over drinks, ask your associate or client to discuss business while walking or working out on exercise equipment.

• Don't know what to do?

  Get a trainer (ask your concierge or local gym) or watch an exercise video. But remember, walking is probably the safest activity. So, go out and enjoy the local culture. Walk downtown, visit the town pool, go roller or ice skating, or take in a hike nearby.

• Not motivated?

  Set a goal. Sign up for a 10K run, a coed soccer team, or a fund-raising bike ride. Knowing you have to perform on the weekend will keep you motivated to work out during the week.

Ultimately, the only way to fit fitness into a busy day is to make it a priority. Pack a pair of sneakers and a set of quick-dry workout clothes on every trip. Then find a comfortable exercise routine that is easy enough for you to do on a regular basis. And get rid of the "all or nothing" mentality - some exercise is always better than nothing.
