1. When doing an IM injection, why would a body builder require a 1 inch needle as opposed to 1.5 inch needle? Im confused because it says those with less muscle mass require shorter needles but don't body builders have alot of muscle mass?

    Picture two people who both weigh 260 lbs.

    One is a body builder who stands 5'8" tall and has a 7% body fat. The other a couch potato who stands 5'4 and has a 26% body fat.

    Say you insert the needle 1/2" into the deltoid region... how much muscle would be penetrated in each patient?
