Avry Neal

Avry Neal

ACSM Certified Personal Trainer 

I have experience working with many of the training methods and classes that Boot Camp Hawaii offers, working with populations from children to elderly and abilities from athletes to sedentary. Including gym workouts, I have been creating body weight and boot camp style training for myself and others in the last year. I feel that a blend of strength, flexibility, core balance and endurance is key in achieving peak physical fitness.

My appreciation and commitment to an athletic and active lifestyle has led me to participate in activities such as cycling, running, rock climbing, hiking, yoga, and sports. In addition, I feel that mental health is imperative to achieve balance and personal wellness. I feel techniques such as meditation, energy healing, chiropractic, mindfulness and positive thought can achieve this balance. I enjoy motivating and inspiring people to achieve their goals by making small changes and lifestyle adjustments that make big impacts.

Earl Bagaoisan

Valdosta State University

After going through ACL surgery twice on the same knee, Earl spent a lot of time in physical therapy to regain strength in his leg and reduce the possibility of a third occurrence, so he can return to the sport he loves, swimming.

As a result, he chose to pursue a Bachelor of Science in Exercise Physiology as a step towards obtaining a Doctorate in Physical Therapy.

Earl has been a registered USA competitive swimmer for over 12 years and was involved in club swimming during the last few years of college. He swam the 5k, 3k, and 1k race at Clemson’s Death Valley open water swim.

Cameron Prendergast

NASM Certified Personal Trainer and 200-hour Yoga Instructor Certified

  • *Honolulu Boot Camp Trainer
  • *Corporate Fitness Trainer
  • *Personal Trainer

Cameron’s fitness background lies primarily in recreational sports, running, surfing and most prominently in yoga.  Throughout college while pursuing a degree in music at the University of Colorado, he found himself spending more time in the gym, the yoga studio and cycling around Denver than playing my guitar.  This was the first indicator that he had probably chosen the wrong passion to pursue.  Regardless, he finished his degree in 2008 and moved to Australia.  After a year of travelling Cameron found himself in sunny Honolulu, once again running and cycling, exchanging the thin Colorado air for the temperate tradewinds of Hawaii and the mountains for the ocean.

Cameron has lived in Honolulu for three years now, and in that time has not only discovered a deep love for the islands, but also an even deeper interest and passion in fitness through running, hiking, cycling and surfing.  Most recently he has immersed himself in yoga, completing a 200-hour yoga teacher training under Dorian Wright at Power Yoga Hawaii.  Cameron has been practicing yoga off and on for 8 years, and finally decided to make it an investment in his goals.  He is also an NASM-certified personal trainer, focusing on body weight training, plyometrics, balance and flexibility training.  Long-term goals involve training in massage therapy and eventually a Masters degree in Physical Therapy.
