Hi just started JKD, was wondering since the syllabus contains grappling do I need to do Bjj as well, I may do a bit for my fitness anyway
Need to? Not really Should you? Yes!!! Even with a grappling component in JKD you are still best served by raising your game in a native discipline and then adapting it....its what I do! (Even if CACC is my art of choice rather than BJJ)
Most of my JKD buddies/ teachers/ former students also study a grappling art. You probably don't need to do bjj, but it's commonly done, won't do you any harm, and may do you some good.
You could always do some of the questionable "OJKD" stuff. You ain't fighting anything but air with that though.
I depends on what your aims are, your daughter trains BJJ, and BJJ is excellent for fitness, so if you want to live longer, and to not have to accept your daughters poor choice in boyfriends when shes a 16 year old you will, but its not mandatory.........
