No, I'm not talking about pride. Although we often think of sticking your chest out as a show of pride, it is also an essential part of good posture. Good posture is very important when running and jogging. Sometimes we tend to let our shoulders slump forward or look down at our feet, which leads to neck and back pain. The solution is to pay attention to good posture when you run. You should keep your head straight and tall, like you trying to touch an invisible ceiling with the top of your head. Stick your chest out and pull your shoulders back, as though you are squeezing your shoulder blades together. And pull your stomach in. No, not to hide your gut, to align your lower back! You want to tilt your pelvis by pulling it in with your abs. So, what does this have to do with shirtlessness? Well, sometimes when guys run shirtless, they tend to be self-conscious about sticking their chest out, fearing they will appear conceited. But remember good posture is important. Be confident, stick your chest out, and your neck and back will thank you!
