On HBA's high school campus, the Dan Liu Gymnasium is considered one of the finest gymnasium facilities in the state. Among other facilities are the 1,200 sq.ft. Geiger Conditioning Center (weight-training/conditioning room), a state-of-the-art athletic training facility, and new locker room facilities. There are outdoor volleyball/basketball courts at both the middle school and the elementary campuses.
HBA has two full-time athletic trainers who serve all of the middle-high school athletes and teams through injury prevention, treatment and rehabilitation, as well as education. In 2014, HBA received the National Athletic Trainers' Association (NATA) Safe Sports School 1st Team Award, which recognizes schools that provide safe athletic environments and highlights the importance of seeking the highest standards possible for the care, injury prevention and treatment for student-athletes. HBA is the first school in the state of Hawaii to receive this distinction. Nearly 250 schools nationwide have won this award.
