Pump Your Arms
If you move them quickly, your feet will follow. (It really works!) Plus, you burn more calories when your upper body is in full swing.
Put Gravity to Work
Tilting forward slightly will quicken your pace. The trick is to find just the right angle for your body, and then stay in that position as you walk. To get just enough of a tilt: Keep your feet planted and your body perfectly straight; then slowly lean forward from your ankles until you must take a step or you'll fall. That's the spot to shoot for.
Tighten Your Tummy
While walking, squeeze your abdominal muscles as though you were trying to fit into your skinny jeans. This simple move saves you energy (by keeping your upper body and hips stable), so you can walk longer.
Take Baby Steps
Long strides actually slow you down: As your heel hits the ground, it acts like a brake. Instead, take swift, short steps, rolling from heel to toe.
