Coach Jamie


Working with a trainer who knows you both in body and in mind, can lead to surpassing your own goals and expectations by working with you to overcome obstacles, barriers and plateaus. In both medicine and fitness, Coach Jamie’s philosophy is to team with her clients and patients to build a plan that is unique and tailored to be effective, efficient and achievable.  Her expertise in neurology and yoga blend together to identify body mechanics and movement patterns that may contribute to aches, pain or injuries and help you maximize your workouts to reach your goals.  

She pays special attention to form in all types of exercise and can work with you on prehab, rehab and corrective exercises to improve posture, joint pain and even some medical conditions like migraines. Cognitive techniques and strategies like breathing exercises are also used to help reframe physical and psychological challenges that may impede your progress and work to improve stress management.

In medical school and during her residency, fitness was Coach Jamie’s key to staying centered and focused. Now, as a successful physician in an academic practice, she is thrilled to be able to return to training others with her unique background and expertise to help others maintain and strengthen the physical body and mind. When she experienced burnout first-hand as a new attending physician, she sought out ways to mitigate burnout for herself and her colleagues. 

She pursued a 3-week intensive 200-hour yoga teacher training program at South Boston Yoga, led by David Vendetti and Todd Skoglund.  Those 3 weeks were transformative in her approach to life, her work and her training.  Her style of coaching and training incorporates ‘body reading’, meaning the way we each uniquely move and hold our muscles at rest and with activity, hands on adjustments and continuous feedback on form and technique. 

After moving to NYC, Coach Jamie started her training with Coach Thor where she has spent countless hours honing skills of boxing, kickboxing, self-defense with drills and sparring and continually learning more techniques for training. Whether you are looking for a drill sergeant, or a gentle guide, Coach Jamie will not disappoint. Always goal driven, honest, she uses body weight exercises like calisthenics and yoga, combined with barbell and kettlebell work in interesting and dynamic ways to keep working out challenging, fun and dynamic.  Build more than lean mass when working with Coach Jamie to strengthen your body, your mind and your confidence.  


Gizmo – Our incredible, strong, smart, stubborn and determined tri-pawd boxer who is 13 years young helps to keep us motivated and driven!  His energy is infectious and when he gives you his big goofy smile you cannot help but smile back.  When Gizmo was diagnosed with osteosarcoma and lost his right hind leg, the HOT FIT NYC family had a benefit class for him to help cover the costs of his treatment.  Now he has been defying the odds for over a year as the most awesome tri-pawd around. He gives back to his HOT FIT family 10 times over what we were able to give him with his infectious smile and positive energy.   

If you ever need to be motivated, come see Gizmo work on his physical therapy, mastering balance and core strength to get back to the hiking, running and wrestling he has always loved.  We can all continue to learn from Gizmo and our furry friends who embody resilience, living in the moment and appreciating the simple pleasures of life. During training he will provide emotional support and sweat removal by way of lots of licks of your ankles, or arms if you are sitting on the floor!

Chaos – His name says it all!  Named not for his antics but for the chaotic nature of life when he joined Coach Jamie in NYC at 3 months old, he has grown into his name in all the most positive ways. His energy and enthusiasm is what enjoying life in NYC is all about!  He has grown and matured with the HOT FIT Family from goofy cheerleader to pace setter for group runs, encouraging each and every person to keep going and push the pace! 

He keeps his brother, Gizmo, young and helps with his physical therapy. He started on his fitness journey by hiking with Gizmo in Maine at 5 months of age and has learned from the best how to train hard.  Chaos’s favorite exercise moves are jump squats, helping people wrap their hands for boxing and helping everyone work their defense by practicing his bounding leaps. When not working out, he can often be found sitting calmly in the doorway of the gym, keenly observing life in NYC and welcoming clients, prospective clients and visitors.
