1. Swing those arms
Turn your walking into a calorie-torching workout by bending your elbows 90 degrees and pumping your arms as you stride. It not only automatically speeds up your pace but helps you burn up to 15% more calories every time you work out. For proper pumping: Trace an arc from your waist to your chest as you swing. Your thumbs should come close to touching your waistband as your elbow goes backward. Also, make sure to keep elbows in and don’t let hands cross past the middle of your chest (in front of your sternum). Too much side-to-side motion drags down your pace.
