Re: boxing gym question
Every gym is completely different.
You get some gyms where the coaches well thats if you can call them coaches dont have a clue and will try and throw you in for sparring against anyone.
In the gyms I've been in it has been within the first month, Has not been full on sparring but more tech sparring just helping you get used to throwing punches an opponent learning to use ring and learning how to create angles and cutting off the ring as well as defence, getting you used to have someone throwing punches at you.
After your comfortable with that and starting to progress then sparring will start to progress
