4. Your Shoulders
Another target area for business men, or all of you guys playing on Facebook all day. Most likely if you are at a desk all day for work, you have rounding of the shoulders.
This means your chest is tight and your back is weak. By the way, national chest day every Monday and bouncing 500 lbs off your chest doesn’t help your posture, it’s only making it worse.
Lay off the chest for a bit and stretch those muscles. Turn your attention to your lats and rhomboids (the muscles between your shoulder blades) to correct your shoulders.
