Many moons ago, I played Kendo and trained in a very traditional style of Karate. Lots of Kata and Kihon but barely any Kumite. Dabbled a little in Akido and JuJitsu but these were very traditional styles and not based around sport.
BJJ is an amazing martial art form and workout!
Really any form of martial art can be performed as we get older and is a great way to stay healthy.
Have fun!
