How to look good when running
Keep your shoulders relaxed.
As you start to get tired, you are more likely to hold your shoulders in a tense position. Not only will this make running even more of a challenge, it will also make you look tense and uncomfortable.
If you want to look good, focus on keeping your shoulders down and relaxed. It is easy to do this without realizing it, so try to remind yourself every now and then to see if your shoulders are starting to creep up.
