Can I add keywords to my YouTube filter?

A fair amount of my youtube time is spent watching strongman and athletic training videos. I guess the filters have picked up on this, because my home page is now full of suggested videos on bodybuilding. But despite spending a lot of time on physical activity and in gyms, I have an extremely low opinion of bodybuilding, and am not remotely interested in watching videos of or about bodybuilders.

I’ve been trying to train the filters by marking dozens of bodybuilding videos “not interested”, but it just won’t learn the difference between strongman, athletic training, and bodybuilding. Can I program the filter with AND and NOT keywords?
