So I recently started playing rugby again for the highschool team, and it's pretty much taking up my off days from grappling and judo. My main sport is judo and grappling. I was just wondering if it would be more beneficial (as a side to grappling/judo) to do rugby or lifting? On one hand I think I get alot of anaerobic work from rugby, as we run hills, live drills, etc. Though the injuries might be plentiful. On the other hand, lifting would help me get stronger for judo, and especially if I'm fighting at +100kg. The guys are usually stronger than me there. So should I lift or should I do rugby? I can do some small lifting at home, but to lift seriously is too much along with judo/nogi grappling and rugby. Should I just get more fit and naturally stronger through rugby, or should I go and lift? I know it's stupid guys, but I'm having a hard time thinking about it.
