Someone told me that if a person has had a couple of fights, they can lead others through boxing training. Certainly having ring experience helps, but that's not the only requirement for being a boxing coach.
In order to be the best they can be in the ring, a boxing coach develops fighters’ skills and technique, physical strength, stamina and mental game. A boxing coach fills many roles depending on the fighters they train: mentor, taskmaster, cheerleader, friend and psychologist parental figure, etc. The coach should be observant with regards to the weaknesses and strengths in their fighters, and develop techniques to help their fighters improve.
The boxing coach also provides to understand their fighters' competition. They should formulate wants to help their fighters overcome any challenge competition would bring.
If you are already attending a boxing gym, some of the best training to become a coach is to pay attention to what your coach, as well as other coaches communicate to fighters about boxing technique. Being observant regarding what works and doesn't are employed in the ring is effective to learning to coach.
