As little as half an hour of walking per day has been proven to improve mood, reduce stress, increase bone density and more. Turning your daily walks into a workout, however, requires a bit more effort than just going for a gentle stroll.
One of the easiest ways you can increase the calorie burning effect of your walks is by playing with the pace. Add some intervals to your walks to see some serious belly fat burning. 2 minutes of low intensity walking, followed by 2 minutes of high intensity, then 30 seconds of jogging will really get the heart racing. This sort of workout forces the body to constantly adjust, using more energy and blasting that fat in the process.
As well as varying the pace, why not try a new route? Pick one with plenty of variation in altitude and terrain. Walking both up and down hill uses different muscles than walking on the flat, try to include some inclines for the best muscle boosting walks. Similarly, diffent terrains have differing effects on your muscles, add some sand or gravel segments to give that added boost to your regime.
It is quite obvious that the more muscle groups you use while exercising, the more energy expenditure there will be. Therefore, try doing something with your arms while walking. Just adding an active bend to them while they naturally swing will help, or you could carry some small hand weights with you to supercharge the exercise.
