A 34-Minute Interval Walking Treadmill Workout That'll Actually Help You Lose Weight

You might think there's no technique to walking, but there's definitely a few posture tips to keep in mind. "Proper form is important for any exercise that you do. When you walk, proper form helps to increase the efficiency of your workout and prevent injury," said Chadwell. Follow these guidelines:

• Look straight ahead, not down at your feet.
• Swing your arms naturally while keeping a bend in your elbow, pumping your arms helps to power your forward movement. Don't hold on to the treadmill handles.
• Brace your abs. This will help keep your back straight.
• Keep a smooth gait by using a heel-to-toe step.
