"Sorry for lifting bro" (SFLB) is statement used to respond to your friends that are trying get you to engage in other activities than going to the gym to training.

"Sorry for lifting bro" can also be used as a rebuttal to jealous comment from other gym goers that make negative comments about you physique to make them selves feel better because they cannot put in the hard work required to achieve similar results.

In short, its a kind way to tell those that are trying to distract or discourage you from reaching your fitness goals to, "go f#$& themselves" and no matter what they say or do, they will not be able to keep you from reaching your fitness goals.
Friends: "you should skip the gym and we should go out and get wasted"
