The gym I found inspiring was here in phoenix,in the back of a warehouse belonging to a construction company. The trainer there is a young guy- early 20s- and he works his kids hard and maybe a bit rough but with a lot of affection. And they all obviously love him to death. Its the only- or one of few- gym I knowof where 30 kids under 15 come in get to work, almost 100% on their own, and actually work until he works his way around to them.
The most aggravating was also here in phoenix where boxers were not allowed to use the mirrors, the ring and there was no sparring.
