Barrier No. 1: I don't have enough time to exercise.

Setting aside time to exercise can be a challenge. Use a little creativity to get the most out of your time.

Squeeze in short walks throughout the day. If you don't have time for a full workout, don't sweat it. Shorter spurts of exercise, such as 10 minutes of walking spaced throughout the day, offer benefits too.

Get up earlier. If your days are packed and the evening hours are just as hectic, get up 30 minutes earlier twice a week to exercise.

Once you've adjusted to early-morning workouts, add another day or two to the routine.
 
Drive less, walk more.

Park in the back row of the parking lot or even a few blocks away and walk to your destination.

Revamp your rituals. Your weekly Saturday matinee with the kids or your best friend could be reborn as your weekly Saturday bike ride, rock-climbing lesson or trip to the pool.
