This is something I commonly see people do when they are walking or jogging.

Unfortunately it does not provide any additional fat burning benefits.

When you burden your body with extra weight, you add stress to your knees, hips and ankles. It also alters your gait (the way you walk and run), which can lead to poor form, bad posture and potential injury.

Furthermore, it can lead to tightness in the arms, shoulders and neck – not good.

You are much better off increasing the intensity of your cardio by incorporating some interval sprints spaced with slower recovery periods. This will boost your metabolism, torch fat and release those wonderful fat-burning hormones!

If you want to hold weights, do it as part of a structured and supervised resistance exercise program
that will ensure you actually achieve the body shaping results you desire.
