Many medical centers co-sponsor mall-walking clubs and provide pins, t-shirts or hats to identify members. Walkers get a head start on shopping in that often-dead first hour of mall opening, a boon especially during holiday shopping. One drawback to walking in the mall can be the monotony of passing the same scenery over and over. But if you belong to a club or simply have a buddy who'll join you on your walks, then you'll not only be held accountable for your workout, but you'll also break up the walk with lively conversation. Afterward, you all can congregate in the food court for a water break and maybe even a healthy breakfast. Now that's a great way to start the day!
