Personal Trainer

I recently finished my service in the United States military, where I was fortunate enough to train and work with elite Naval Special Operations team members. The lessons they taught me, and the confidence I received from their training program, is something I will carry with me every day, and would like to be able to pass on to you. Through proper goal setting, commitment, and the right motivation, absolutely anything is possible! Prior to the military, I graduated with a B.A. in Physical Education from Monmouth College, where I was a six-time conference pole vault champion and two-time NCAA qualifier. In addition to track and field, I have also competed in wrestling, soccer, football, and a whole host of martial arts. I believe in living a healthy lifestyle, focused around a well-balanced diet, and proper exercise. My experience in training ranges from both athletes to non-athletes of all ages. I can’t wait to help you achieve your goals!

Dorie Litten

Personal Trainer, Gravity Trainer

Two and a half years ago I walked into the HAC as a stay at home mom, who really knew nothing about fitness. I quickly learned how much enjoyment and energy I got out of my workouts. I have always enjoyed helping others and found a passion in fitness I never knew existed. Becoming a certified personal trainer, for me, was an opportunity to combine my passion for helping others reach their goals with my passion for fitness. If you’re looking to gain confidence, energy, and a healthier outlook on life, come give it a try! Let me help you achieve your fitness goals!

It wasn’t until after 40 that Holly truly discovered fitness. She was informed that a hip replacement was in her future and she quickly learned the importance of fitness in her life. It became so instrumental in Holly’s life (both pre and post surgery) that she ultimately pursued options to become a Certified Personal Trainer. Through her personal journey she learned just how much she enjoys motivating people, especially those over 40. Holly learned that nothing can hold her back, except for herself. She is excited to be a part of the Gravity Training Team at the HAC - let her show you how fitness can be fun,exciting and help you achieve your personal fitness goals to being the best you possible!

Eoghan Brennan

Eoghan Brennan

Personal Trainer, HAC Zone Trainer

Eoghan developed a love for fitness and bodybuilding at a young age. While most high school kids were managing their facebook profiles or carefully tweaking their fantasy football roster, Eoghan was training, getting stronger, and educating himself about fitness and the human body. His philosophy in the gym has always boiled down to training hard and heavy, but equally as important, smart and with precision. “ The greatest secret no one wants to tell in the gym is that there truly are no secrets. There are no miracle workouts, no magic pills, or 3-minute ab exercises. Your success in the gym comes down to the same deciding factors that govern your success in any other endeavor, hard work and dedication to your goals. Those who learn to savor the process of becoming a stronger version of themselves will ultimately succeed over those who act only with the end in mind.”
