Beginning exercisers often ask doctors or other health professionals "What's the best time to workout?" The noncommittal, yet correct, answer is "Whatever works best for you." In other words, the best time for an activity is when you're most likely to do it — consistently. That means selecting a time you can keep nearly every day, without other obligations interfering.

For walking, many people find first thing in the morning works best because it's the part of the day that's least likely to be interrupted, so it's easier to get into a routine. And some studies show that people who exercise in the morning are most likely to stick with it long term. There's even evidence to suggest morning exercisers are better able to manage their weight.

Up and at 'Em

If you've had trouble staying consistent with exercise, consider walking in the wee hours of the day. It will require some adjustments, but you can do it. The first few times your alarm sounds earlier than usual, it may be a struggle getting out of bed — but it won't be long before you're feeling the energy boost that comes from an early morning walk. Try these tips for a.m. walking:

• Wake up in time to see the sunrise during your walk
  
• Wear light-colored clothing or a reflective vest; it may be difficult for drivers to see you in the dawn light
  
• Allow time for some simple stretches before you set out; after a full night's sleep your body is bound to be a little stiff
  
• Wear layers; depending on the season, the cool morning temperature may start to rise while you're walking
  
• You may not want to eat a full breakfast before your walk, but at least have a small piece of fruit, some yogurt, or a slice of toast for energy

Be sure to adjust bedtime if you're getting up earlier to exercise — a good night's sleep is as important to your health as your morning workout.

A walk in the early hours will energize your body and give you a sense of accomplishment to carry you through the day.
