Professional Fitness Trainer
Originally from New York, Jen developed her passion for fitness at a young age as a competitive swimmer. After obtaining her Bachelors and Masters degree in Criminal Justice from Niagara University and relocating to San Diego, the pull she felt toward helping others achieve their fitness and health goals became undeniable. Her path changed direction and she went on to obtain a Certificate in Personal Fitness Training from National University. She is currently certified with the American Council on Exercise, and is CPR/AED certified.
The sense of strength and motivation she gained from competing as a Division I athlete is something she now seeks to inspire in others. Her training philosophy stems from her commitment to instilling a sense of joy, confidence, and strength in others through fitness and healthy lifestyle choices, in a fun and supportive environment. She enjoys encouraging others to feel the sense of empowerment and well-being that stems from the journey toward better health, and from establishing lifestyle changes that reap long-term health benefits.
She has completed the San Diego Rock N Roll marathon and numerous half marathons in San Diego, and actively participates in yoga and strength training.

When I first walked into the Greenasium, I fell in love with it immediately. I felt instantly comfortable. Then I had my first session with Jennifer as my trainer and fell in love with it even more. Jen is an amazing trainer. She sets the bar high, but knows exactly how much to push you. Her training session are always different, so there is lots of variety and the workouts are amazing. She is a stickler for form and pays close attention to every movement to ensure that you are doing it right and getting the maximum benefit. In addition to that, she is a lovely young woman (I am 66 so I can say those kinds of things) and fun to work with. — Jackie S.
Fridays are the days I see Jen Bellenger for training. I always know, no matter how off track I get during the week I will be put right again on Friday. Jen is a terrific trainer— she is a stickler for perfect form in any given exercise, so I always know I’m doing it correctly, and not wasting my time. My workout is always just tough enough, I always feel like I have achieved something new. She has brought me from my jelly-bowl former self into a much tighter, leaner, stronger healthier me. And that is a good thing. This combined with her bright smile, sunny personality, and encouraging demeanor make her the best trainer I’ve ever worked with. — Elsa M.
As my personal trainer since September 2011 at Greenasium, Ms. Jen Bellenger is simply the best of the best, and truly cares about my overall health. She motivates me, coaches me and most important, educates me correctly about implementing a wide variety of exercises I can do at home, at the beach and at work. She always has a positive attitude, smiles a lot and always mixes up my exercise routines to keep it fresh and challenging. I like how she tailors my personal exercise program to fit and meet my health goals. I highly recommend Jen Bellenger to be your next personal trainer. — Don Q.
I have returned to Southern California after 26 years in Massachusetts. The hardest part of moving is finding a new dentist, hair dresser etc. I worked out at a small indoor circuit type “Boot Camp” in Massachusetts and knew I wouldn’t be able to find anything like it here. I had gained weight during the move due to the stress of looking for a new job, a new home and the upheaval that comes with everything new. I found the Greenasium after doing a google search for Zumba. I went in for the free assessment and liked the relaxed and green vibe of the place. I was matched up with Jen as my trainer and tried a Dynamic Stretch class as part of the free assessment. I never could have dreamed that I would find a second home in a gym. I have tried the big gym membership and found it wasn’t for me. I love what someone said about the Greenasium, “It is the Cheers of the Gym World” Everyone knows you and you can be as social as you want. It has become a family to me. The variety of classes is great and I like the way that you sign up and pay for a trainer and get the whole gym as a part of the price. The accountability of having someone map out your exercise plan for the week is something that keeps me on track. I can’t say enough about the level of professionalism shown by Jen and the rest of the staff at the Greenasium. I am impressed by Jen’s knowledge, patience and her ability to get me motivated each time I work out with her. I love the commitment to keeping everything in the gym green and sustainable. That is something close to my heart and being around people who also love & live that way is inspiring.The Greenasium is a unique place and the fact that it is the culmination of a dream for 3 guys is especially inspiring for the people who get to live that dream with them. — Lia E.
