Three is the magic number at Trinity Exercise Studio. The staff there lead exercise classes that concentrate on three aspects of fitness: cardio, strength, and flexibility. But those aren't the only requirements—each class must also aim to nurture each client's mind, body, and spirit, taking a tri-fold approach to total health. For that reason, the schedule includes disciplines such as boot camp classes, yoga workouts, and TRX suspension training, which challenge participants both mentally and physically. Trinity's trainers also supplement these group workouts with personal training and nutritional counseling.

Three is also the age of some of Trinity Exercise Studio's youngest clients. In addition to helping adults get in shape, the studio offers youth programs for ages 3-12, as well as teen programs, senior citizen programs, and summer programs for people named summer.
