I have done various stuff over the years.
jits is great. Probably my number one recomendation for overall benefit. Fitness, self defense and just fun. If you want to add some striking to the mix, I would look for an MMA gym that is doing a lot of mixing and matching or a muy Thai gym or kick boxing or plain boxing in that order. I did and love a lot of traditional martial arts over the years but think for self defense, there are just better options these days That weren’t around when I was a kid watching Chuck Norris and JCVD movies and dreaming of being a black belt.
if you do anything but in particular jits, play smart And for longevity. Most of the guys I know that have done that for a long time come away with health issues. Elbows and shoulders from not tapping. Knees and hips from throws. Neck and spine from an accumulation of evil. everyone I know that went above blue belt (+2-3 years)has some degree of spine issues after a time. Most of the top players and many black belts have to have spine surgery in middle age. Some are more open about it than others. I spent a few years at the renzo Gracie gym in NYC. Big gym. Lots of VERY good players. I am a bigger guy and tried to “run with the bulls” too much even though I was 10+ years older than the 20 something crowd. When a couple of +250 pounders start tossing each other around, it takes a toll. I “retired“ after a blown shoulder. Focus on learning and flowing with the techniques. Protect yourself and your partners.
finally, martial arts are great for confidence and fitness but real fighting is a whole other thing. if you go hands on at work, make sure you know what you are getting into both I t terms of safety and liability. Consider various other self defense options. Sprays, stun guns, knives, saps, batons, real guns. I know a couple of ER workers and paramedics that carry under their scrubs or uniforms. wrestling some asshole to the ground and putting him in the king fu grip is cool And all but thumping him behind the ear with a blackjack a few times until he takes an unscheduled nap may be a better choice.
