@ARIZE decided to tag you man
Ah shit, sorry man, I've must have missed the tag...
I'm 100% behind your decision... I used to move a lot, so I've changed gyms and trainers a lot. But I've also changed gyms by choice. My first trainer was an old school Thai guy in France. He made me the fighter I am today (stylishly), but he also put the bases on what I consider a proper training session for "serious" fighters. Every other trainer I had, I automatically compared them to him. So when I felt that the level or type of training is not good for me, i don't hesitate, I change gyms... But I make sure I can find something better.
If I wake up a day, and i find myself thinking that I need to train a lot more at my home gym, with the help of some friends... that means there is a problem.
The only time I didn't change gyms even with that feeling, it was because after 2 years there, I had a good relation with the guy and we talked about it. Basically it started as a small gym for pros, but was becoming more of a fitness camp... I stayed 6 more month, but it was getting slowly back to a cross fit thing...
But the main reason I've changed gyms, it's because the trainer wasn't preparing me in my style... I' ve changed gym because one of them was too much into punching combination... I don't use a 6 punch combination in my matches, so to spend an entire month drilling it for example, is a waste of time for me. Another one dint train clinch almost at all.
I need a guy that can adapt his training to my needs, to my style, and not the other way around. (Hell, one of my best experiences, was in a TKD ITF gym, because the guy was very open minded, and was trying to teach me stuffs that I could use in MT, and not just for TKD. He adapted his classes in a way I could beneficiate from it, but still teaching his art. I started there when i couldn't find a decent MT gym, and dint want to loose agility and speed, and finally stayed many more years cross training..)
And that's without the classic "MT gym", but in reality it's a KB one... no clinch, no elbows and some times not even knees...
Or the professional gyms... without a ring.
Another reason I left a gym, was because I was becoming slowly the second trainer there... I don't mind helping every now and then, spend time (that I pay) with some beginner that needs help drilling or explaining something. Because I remember when I was one, it was cool from the more experienced guys to give me pointers etc... But there is a limit. There is a difference from: helping as an experienced guy, and do the trainers job for free.
I understand the concept of "loyalty" to a trainer, to a gym... But when someone at your level, feel it in his guts that something is wrong, something is missing with the training, you gotta go. You are not a beginner, you know what you need... Just make sure you go somewhere that has it.
Since I've been to a lot of different gyms, I've gathered a good amount of experiences, and I know early if it will do for me or not. Of course, the trainers must get to know you, and that may take some time, but you can see how they train the other fighters... I also spend some time after class to talk about my style with them, ask their opinion about it, and see how they respond.
Another think is that I'm not a very social person when I go train... I go to the gym, I train, I go back home... I don't really socialize with those guys, I don't hang with them, I don't do activities they organize. So I may have a good relation, but we are not close friends usually, we are not "family". So I never felt that I "betrayed" them. I'm just not a satisfied client...
Now, if you are at a gym and you train there for free, or even get payed by them to represent them, to attract clients, or to help with classes, then you should talk about it. But if you' re a just client, and if you're not satisfied with the quality of what they sell, you made the right call, and there is nothing wrong about it...
Anyway, that's my experiences with it, my opinion about it... And I can understand others having a different view about it. (Except the part about the 6 punches combo in MT...)
