Big difference between both.
Working muscles are muscles that are rugged and brought fourth by hard work either in your job or around the house landscaping.
Vanity muscles (Be There, Wes) are muscles that are made for the Speedo/Thong. They're basically useless. People that have Vanity muscles can't pick up a toilet to change a wax seal, hold drywall up to finish a wall.
Vanity muscles are made to be oiled up and have the sun kiss them.
Working muscles are made for sweating and pulsing when in action.
Vanity muscles look good when seersucker is draped upon them.
Working muscles appear rugged when jeans and Carhart jackets lay on them.
Vanity muscles seem to have their own voice (Andy Dick, James Corden, Perez Hiton)
Working muscles seem to have a different voice (Clint Eastwood, Charles Bronson, Steve McQueen)
Vanity muscles get pulls and aches quicker
Working muscles ignore all futile attempts of weakness.
Vanity muscles love selfies
Working muscles would rather smash the camera
STAY POSITIVE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
