Lifting weights to spite people who'd fat-shame my girlfriend

One reason why I lift weights is to spite the people who would say about my girlfriend, "She's so fat; how did she get a guy so athletic?"

Back in her schoolgirl years, my girlfriend used to be bullied to an extent by some asshats, particularly for her weight. She actually lost a little bit of weight last year (unintentionally), but at her heaviest, she probably weighed over 250 pounds, maybe even closer to 300. She says she likes the "swimmer body" type on a guy. I'm very glad that she's pleased with my physique, and another bonus is letting people such as her former bullies eat their hearts out when they see that I'm with her and not with them.
