All boys take part in an extensive physical education programme. PE lessons include gymnastics, music and movement, basketball, volleyball, health related fitness and athletics. Some of the older pupils use local leisure centre facilities to do rock climbing, badminton, tennis and cricket nets.
Team games are played at the School's seven-acre playing fields at Canons Park. Older boys play twice a week, younger boys once a week. All the major games are included: football, rugby, hockey, cricket, tennis, athletics and cross-country running. Matches are played against other prep schools, with some fixtures being played at the weekend.
Fixture lists are extensive with A to E teams often representing each year group to ensure that every boy has the opportunity to represent Arnold House. Boys also have the opportunity to compete for their Houses in a variety of sports competitions. Regular sports tours also take place, in particular for rugby and cricket.
A wide range of extra-curricular activities operate after school, including amongst others gymnastics, football, basketball, cricket, running and Taekwondo clubs.
