I'm 50 and krav maga is one art I want to train before I hit 60.If you can do it so can IThere are 4 in my area, of those I have narrowed that down to 2. The one I am going to does not offer short cut instructors training. The other is an incredibly reputable MMA/BJJ/Muay Thai school. They added Krav Maga a couple years ago, but they recently added a week long instructors class too, this made me wonder. The other 2; 1 looks good but it is incredibly expensive and the furthest away. The other is the closest but they do not respond to phone calls and have no e-mail address... and I have had dealings with the head instructor when he was running a Wing Chun School, he is a good guy, but his adding religion into things and then becoming a private police training academy (which still exists) make me a bit nervous.
I am on this bent of wanting to get back into some harder training of late, I'm thinking this might be my mid-life crisis (since I have not had one yet and I am closer to 60 than 50 ) If school 1 does not work there is school 2 to consider, If those fail and I survive there is a JKD school that is rather close and rather good I will check (I plan to check it out anyway) there is also a BJJ school, but they are as far away as the expensive Krav Maga school, and I will admit right now, I am impressed by BJJ, but I am not a BJJ guy. If I were to go to that school it would likely only be for the 3 month basic program. And there is also a Systema guy I discovered not to long ago.....And lastly there is also a guy teaching modern wushu in my area who use to teach Sanshou,, and a few years back he tried to convince me to go there.... so that to might be a possibility as well as a Chinese based style and I have been a CMA guy now for over 20 years.
I am guessing if I survive, and/or get that far, this mid-life crisis thing will be over and I can go back to my Taijiquan and Xingyiquan
