Day 13: Stroll Out

Leave your car in the garage, grab your roomie and your dog (or borrow a friends!) and take a stroll. There’s nothing better than a nice morning walk. Stop by the farmers market, grab a coffee, window shop. After all, walking really is the best exercise. Check out our tips for losing weight while walking!

Walk this way. When it comes to walking, your body and brain know what to do. Makes sense — you've been doing it since you took those first wobbly baby steps. But with these three form fixes, you'll maximize your burn, big time.

Chin up. Your gaze shouldn't be aimed at your feet, no matter how snazzy your sneakers are. Instead, focus on a point about 10 feet ahead of you. This will keep your stride longer and your neck comfortably in line with your spine.

Activate your abs. When you engage your core — pulling your belly button toward your spine— you automatically trigger good posture. 

Squeeze your glutes. Your backside literally propels you through your walk. To get the most oomph — so you can go longer and faster — keep your glutes tight. Bad visual, good strategy: Imagine squeezing a winning lottery ticket between your cheeks.

4 ways to burn more fat. So you're the impatient type? Use these tricks to up the challenge and calorie burn.

Add hills. When you hit the hills on a treadmill or in your neighborhood, you increase your calorie burn by nearly 20 percent — and that's just on a one to five percent incline.

Go off-road. Head out for a light but brisk hike and you'll torch about 430 calories in just an hour. Credit the uneven terrain — which forces you to work harder. Sub this in for one of your weekly power walks.

Swing your arms. With elbows bent at 90 degrees and hands in loose fists, move your arms in an arc, keeping elbows tight to your body. This helps drive you forward, says Weltman, builds upper-body strength and can increase your burn by up to 10 percent.

Make longer strides. Instead of taking more steps, "work on increasing your stride length," Weltman says. "You'll cover more ground," and that means more fat fried.
