That's because it's a sport that's all about getting in the zone, floating like butterflies and stinging like bees - a sport where every step, jab or cross counts.
But we'd imagine it'd be difficult to keep that focus if, say, one of Hollywood's hottest talents dropped in unannounced.
That is exactly what happened to a lucky group of kids in Lambeth, London, who spent the day hanging out with a famous face from the new Creed II film.

The boxing gym in Lambeth is run by Black Prince Trust, which offers first-class sports and education facilities to the local community and schools. One of its key partners is Fight 4 Change - an initiative which provides boxing, martial arts and fitness training to support, mentor and progress marginalised young people and those at risk of offending in deprived communities.
