Are you concerned about your posture??
Well check out this simple and effective posture test that you can do if you have an available wall!
Yeah, the video might be directed toward golfers primarily, but this method will show anyone if there is a red flag with their posture.
"The more common version of the wall test for checking posture also has you stand against the wall with your feet about six inches away, but instead of pressing your back flat against the wall, just have your head, shoulders, and butt touch the wall. Place your hand between your lower back and the wall and then again between your neck and the wall. If you can get within an inch or two at the low back and two at the neck, you're in good shape. Otherwise, adjust your posture to get the ideal two inches of space. For example, if there's too much space, tighten your abs and try to maintain that throughout the day."
Try it out, and if you need to, correct the issue! Posture is super important in all areas of your life!
