Jui Jitsu

M/T are my rest days.

W/Th/F/S/S are my weight lifting days.

I just started jui jitsu, on M/T.

This puts me in a lurch with no rest days. I don't want to lose what muscle I have gained. How do I incorporate lifting and jui jitsu!?

(I work M until 3, and jui is at 530, so it would be asking a lot to fit in a lift to piggy back on the day).
