I probably should I've had my muscles measured, and my legs and butt are 30% stronger than "normal", while other muscles are "normal"
Tennis made my legs strong
I should concentrate on arms tbh
I used to be laxed with leg days but all of a sudden my back/shoulders expanded. So now I make sure to do it at least once in week/term because I like to wear skinny jeans and don't want to look like Jonny bravo.
And because I never used to run or cycle my calves are crazy underdeveloped but they are the most boring annoying muscles to work out
