5"8, 180 lbs, just turned 34, I'm in decent shape and about to join a boxing gym in two months with zero experience.

In the meantime I'm doing insanity max 30 and dig deeper to get conditioned while I slowly buy gear and equipment to practice at home too.

Anything I should know? How does free gym use even work? Will coaches only help you on one on one lessons and group classes? Will I even learn to really box from the group classes considering everyone is at a different level? Do I HAVE to get 1 on 1 classes if I wanna actually learn?
