What is guy skipped leg day?

"Skipped leg day" is a common gym slang term used to refer to an individual who neglects to train their lower body muscles. This results in an unproportionate physique where the upper body appears muscular while the legs remain skinny or weak. The term is often used humorously to point out someone's lack of lower body strength or development. It's important to train both upper and lower body muscles to maintain a balanced physique and prevent muscle imbalances, injuries, and posture problems.
