Middle-of-the-road moderate.
I have never lifted weights in my life, nor lost a fight to my brothers who do. Though that might have more to do with my being unquestionably the meanest of the bunch.

Anyway, my one brother is the least physically active of all of us, and the smallest & lightest by a long shot, and when we were both in high school, we took different sections of the same environmental science class. On a parent-teacher event, the teacher characterized us by saying what a jarring contrast it was to have my brother going along and giving back the book's answers on every question in his first period, and then in the later period, to have me fighting him tooth and nail. He has, however, become more interested in football in recent years, but they say a lot of people become more conservative when they get married and settle down (he has sired three active and hirsuite sons in the last nine years, so I don't think you can question his manliness). My three most politically active & informed brothers are the three who lift weights recreationally, and they are roughly the same ideology as me (two of them are more than a decade younger, so they listen to us on political issues, which helps).
