Thatās actually very sound advice. I never even thought of that aspect.
Hereās an analogy...
Cus DāAmatoās boxing gym in Catskill, NY had impeccable credentials. Letās say you signed up strictly because of this. You join, DāAmato, Rooney, and Atlas pretty much ignore you, giving you all of 5 minutes of their time each day. Every day, you get to spar Tyson who beats the living snot out of you and doesnāt care because he all he and they need is a fresh punching bag for Iron Mike.
Great credentials. Great instruction. Great fighter(s) coming out of that gym. How great is it for you?
I donāt think thatās how it went at DāAmatoās gym, and im highly doubtful thatās how itāll be where youāre looking at. But you donāt know how anything is being run until you walk through the door. The teacher could be great, spend a lot of time with you individually, and have virtually no students (which has pros and cons). He could run a great sized gym and give everyone the attention they need. He could push his teaching of newbies and intermediates off on an assistant. Thereās no way to tell from a website.
Credentials should get you in the door. Whatās going on on the mats should determine if you stay or go elsewhere.
I restarted karate going on 4 years ago after a 15 year hiatus. One of the places that caught my eye was a school not far from my home. The CIās teacher has impeccable credentials in the karate world. I know a few respected local karate guys who trained with the CI or under him. They had nothing but great things to say about him. That got me in the door to visit. I didnāt walk in and say āwhere do I sign up?ā I watched him teach a class. About 5 minutes after warmups my mind was made up. But I watched 2 full classes on different nights to confirm what I was seeing wasnāt a fluke or horse and pony show.
I could tell he was an excellent teacher, his students were similar to me in background and goals, and I felt at home. I visited other schools that were great on paper too. They didnāt do it for me.
