The responsibilities of a boxing instructor include teaching a variety of age groups how to box and improve their skills in the sport. You also provide athletes with new techniques they can practice and incorporate into their own boxing style. There are opportunities to work with kids as well as adults, one-on-one and in groups. Training sessions are held in a casual gym setting as a group fitness class with the goal of providing a rigorous exercise session that is fun, challenging, and encourages members to sign up again. There are also serious athletes who need private coaching, which includes duties such as sparring while you demonstrate new skills and preparing each boxer for a competitive match in a boxing ring.
