Insta thinks I'm a bodybuilder?

Do you know that feeling when Instagram always shows you things you're not interested in? I play handball and go to the gym. I don't follow any athletes or anything, just friends. But all I see are videos of posers showing off their bodies, or even of bodybuilders who look totally abnormal. Why is this being shown to me? I only train normally and don't want to be a bodybuilder, but Instagram is like, "It wants to see guys with their shirts off, showing off their muscles."
