What People Are Saying…

“I discovered boxing with Jennifer Santiago’s class at the Printing House Gym a few years ago. In the past, I was intimidated by boxing because I felt that it was a man’s sport. I decided to join Jennifer’s class and I did not regret it. She taught me so much with regard to form and discipline. I really enjoy her as a trainer and I hope that I will get to work with her again soon'“

“As a former elite athlete, I had one goal in mind – to regain my athletic status through training like a boxer trains. In one short year, Jennifer has re-shaped my athletic foundation and gotten me hooked on boxing. If you’re serious and willing to commit to the demands of boxing, team up with Jennifer. You’ll have no regrets, be the envy of your friends, and meet one remarkable woman in the process.”

— SARAH JOOS

“I have worked with Jen for over 3 years. I am a competitive athlete who was looking to mix up my training, learn some boxing skills and increase my strength and conditioning. Jen helped me to exceed all of my goals through her dedication, energy and creativity. Jen is a phenomenal trainer. She is committed, passionate and really fun. As a boxer/ professional fighter, Jen’s skills – and ability to teach them to a white guy with no rhythm – are awesome! I really looked forward to our workouts and had so much fun in our sessions. If there is one thing I would emphasize it is Jen’s creativity – no two sessions have been the same in over 3 years. That has kept me interested and improving. I am proud of my achievements and excited to have Jen as my trainer and as my friend!

“Jen is a force of life on every level! She balances patience with her clients, while pushing them to meet their highest potential. Her awareness of anatomy, her sense of the human spirit, and her experience in the ring distinguish her from all the wannabe’s! She’s the real deal. She helped me to reach my pinnacle in terms of fitness. 3 years into our partnership – I was diagnosed with a condition that put me into the hospital for 10 days – I left the infirmary having to rebuild so much of what she and I accomplished. Her compassion, understanding of who I am, the drive I had to comeback, knowing when to push me – made it all an amazing journey to regain my strength and endurance. I could never have made the recovery I did without her. I was blessed to have her with me. I could go on and on about her…bottom line – JEN ROCKS! I love and respect her in countless ways, and you’ll be lucky to train with her and get to know her along the way.
Don’t Stop/Can’t Stop!”

“When I signed up to train with Jennifer Santiago, I felt like I was part of an elite club of fighters. She treats me with such care and concern, like my muscles were her muscles, she knows when I over stretch or lift too much. She reads my eyes, she knows when to push me, to joke with me and how to relax me. The coolest thing is that she has her own language, born from growing up training, but honed from being such a sensitive, caring person. Cat-dog, sun fists, counting backwards. She taught me how to fight, she taught my son since he was 2, my daughter shadow boxes with me everyday. She changed my life. I am part of an elite club, I am a fighter.”

— BOB SPEIGEL

I’ve been working out with Jennifer for over 4 years now because she is the best around. Her enthusiasm makes it obvious that she loves training, and she has the experience both in and out of the ring to back it up. She will make you work hard to reach your goals no matter what level you’re at.”

— JOHN GOLDSCHMIDT

When I started training with Jen I knew nothing of boxing, my core or balance-I was a once in awhile (when the mood strikes me) gym person. She made me feel so comfortable from the start with her warm personality, sense of humor and in depth knowledge. She set me on a path to find my own fearlessness and how to throw a good combination punch. Now I’m at the gym 3-4 days a week because I realize how wonderful it feels to have your body work for you. I owe that to Jen.”

— LORRAINE MATTOX

“Like the Acinetobacter baumannii, Jen Santiago is both tiny and dangerous.  She can adapt to beat any defenses and has no mercy on those who try to eradicate her.  Despite this, she is very sweet and fun to be around.  She’s just a gentle miniature giantess.”

— HENRY SIMONDS

“Jennifer Santiago is a fantastic & inspiring trainer: she possesses the perfect combination of technical skill, intensity & compassion. I highly recommend her!”

— SAMERA NASSERDIN

“Simply stated, Jennifer Santiago is an amazing trainer. I have no time; little patience and I always find time to train with J5 Fitness. Jennifer matches my effort, accommodates my physical challenges and keeps it fresh and fun. She is a key reason why I can still walk today, despite the dire predictions of my doctors. When it comes to trainers, it doesn’t get any better than J5 Fitness. Invest in yourself, the payback is awesome…

— DOROTHY REGAN

“Jen Santiago has been my trainer for eight years now, during which time I have gone from 48 to 38 years old. She is a master, a brilliant trainer, and a total love.”
