A boxer is a person who fights in the sport of boxing.
Boxers are often associated with professional or amateur fighting competitions, but the term can also refer to someone who participates in sparring sessions for training. Many gyms and fitness centers offer boxing classes as a way to improve physical fitness, especially hand-eye coordination and punching technique. These classes usually involve pairs of people "boxing" each other while wearing gloves for safety.
