For some of the boys out there who are feeling insecure about their bodies, I want you to look at some Olympic athletes:
Mo Farah, 10000m gold medal winner. He’s quite small and doesn’t have huge muscles. But he’s still a champion
Lasha Talakhadze, weightlifting gold medal winner. He’s not skinny; he clearly has body fat and a rounded face. But he’s still a champion
Kōhei Uchimura, gymnastics gold medal winner. He’s muscular, but is only 1.61m tall (5ft 3″). But he’s still a champion
So what I’m trying to say is that men and boys are often given expectations to be muscular, thin and tall - the diversity in male Olympics athletes shows that you absolutely do not need to be all/any of those things to be valid. You and your body are valid no matter what.
