1.Walk this way
If you have diabetes (or worry about getting it), consider this: Exercise improves your body's ability to control blood sugar. "It's not just during exercise; the effect can last 48 hours afterward," says George King, MD, author of The Diabetes Reset. When you're active, your muscle cells become more sensitive to insulin, absorbing larger amounts of glucose. Over time, regular exercise can help you shed weight. And you don't need to do CrossFit. "Even walking can be incredibly helpful," Dr. King points out. A few tweaks to your form can mean a much better workout for your heart and muscles (plus more calories torched!). Here's how to boost your burn with every step.

2.Wear a heart rate monitor
It's like having your own coach to keep you at optimal intensity (about 75 percent of your max heart rate). "It can give you a nudge if you slow down," says Therese Iknoian, author of Fitness Walking.

3.Count your steps
Research shows that people who wear a pedometer walkabout 2,000 more steps per day. Apps like Pedometer++ and Accupedo can have the same inspiring effect.

4.Make a loose fist
Clenching your hands just wastes energy that could be used to power your walk.
