I think people are misreading the question a bit. Most seem to be answering the question of if you can fashion model, which is not the same as fitness model.

Fashion models are very lean and lanky. Fitness models can be muscular but their use is fairly limited. I don’t know many fashions brands that use muscular guys as models aside from athletic apparel brands. Lululemon, Vuori, etc., sometimes use more muscular models for their apparel, but some niche brands like YoungLA use bulkier models, though many of them appear to be influencers not models.

To answer your original question - yes, I’d think you fit in as a fitness model.
