Boston Staff


Mike Farina, CPT

Mike Farina is a former Coast Guardsman who is deeply committed to the health and fitness level of our membership. Nationally certified as a Personal Trainer by the American College of Sports Medicine, Mike is best known around the club as the guy that rode his bicycle from Boston to San Diego., racking up 6,000 miles of travel along the way. Why? You’ll have to ask him. Mike spends most of his time at ZONE5 but when not here enjoys basketball and running. He lives in Wakefield, MA and lives to serve. If there’s anything we can do for you, Mike’s the guy to see.

Kadeja Gaines

Kadeja, originally from Germany, recently moved to Boston from Minneapolis to work for Nike. She graduated from the University of Norte Dame where she majored in psychology and German. Kadeja is a RIPPED certified instructor and a certified group fitness instructor through the National Exercise Trainers Association. Kadeja grew up competing in track and field, gymnastics, and dance. As a high school sprinter, Kadeja competed in the American-European championships. She played competitive flag football after college but this was cut short due to a major ACL injury. Her recovery from this injury is what originally inspired her to coach and mentor others through fitness.

Other than training, Kadeja loves salsa dancing, trivia nights, celebrity gossip, and bad puns… like really corny ones that she loves busting out in class from time to time!

Julianne Cappello

Growing up as a dancer, Julianne has always had a passion for movement and an appreciation for health and fitness. While studying at Suffolk, Julianne was a member and captain of the Suffolk University Dance Team (SUDC) for all four years.  Throughout her dance career, she participated in competitions both at a young age and during her college career with her teammates on SUDC. Julianne initially joined ZONE5 as a member, but after becoming enthusiastically devoted (some may say addicted) to the high intensity interval training, it wasn’t long before she was an instructor herself. Julianne is also a business development director at a marketing firm in Downtown Boston and can relate to the clientele looking for a release or escape from the stresses of work. She makes sure her classes leave everyone feeling accomplished and stress free.
