Tiffany Chag

MS Exercise Physiology and Nutrition

Registered Dietician

NSCA - CSCS

NASM - CPT

My passion for health and wellness is personal as well as professional. When I was playing soccer as a student athlete at Boston University, I suffered bilateral ACL tears followed by compartment syndrome and experienced first-hand the frustration of injury and the patience needed for the recovery process. I also know that the payoff can be huge: The year after I graduated, I ran my first marathon. Six months later, I completed a second. I wasn’t fast; it wasn’t pretty, and I definitely didn’t have a “runner’s body.” But what amazed me about that experience was my body’s capacity to accomplish something I never thought possible. I changed my exercise habits; I changed my eating habits, and a whole new world opened up to me.

I love helping my clients reach their own goals. As an exercise physiologist and registered dietician with more than 15 years of experience in the field, I have worked with a diverse population of clients ranging from youth and collegiate athletes to people managing chronic disease and recovering from serious injuries.

I completed my master’s degree in exercise physiology and nutrition from Columbia University with a focus on sports nutrition and performance for female collegiate athletes. I am also a National Strength and Conditioning Association Certified Strength and Conditioning Specialist and a National Academy of Sports Medicine Certified Personal Trainer.

What They Say...

 

  • I have been training with Tiffany for over six years now and could not be happier with my fitness results.  Tiffany designed custom programs for me in preparation for my wedding, as well as during and after my pregnancy.  She offers complete programs that not only focus on exercise, but also nutrition. Her sessions are varied, challenging and also fun and enjoyable. Best of all, Tiffany is a great motivator and an absolute pleasure to spend time with. I cannot recommend her enough! - S Drvostep (NYC)

  • Tiffany is the best trainer/nutritionist/fitness guide EVER!  She has completely changed my fitness and food and exercise philosophy---and I really did think I knew it all!  Tiffany's guidance and nutrition recommendations and training take into account where you are in your fitness journey, allows for any joint issues/limitations, and manages to transform the body over time!  I am stronger than I have ever been in my life, I have more confidence, and I am more knowledgeable about the mechanics of my body.  Tiffany is exceptional:  her workouts are motivating and she consistently pushes me to go a bit further, without ever going too far.......she's fun, smart, and a lovely and kind human being.  Her nutrition guidance is balanced and she sets attainable and realistic goals!   I have recommended her to friends and family, she is truly one of a kind.  I am so grateful to have found her and I cannot emphasize enough how amazing it is to work with her---LIFE CHANGING! - J Sudduth (NYC)

  • "Tiffany Chag stood out not only as a focused, confident and motivating coach to her clients, but as an accomplished athlete herself. Knowing that a trainer with this level of leadership and professionalism is a rare find. Tiffany is someone who always wants to know more, why, how. She attracts people to her who are looking for the same. Trainers and clients alike look to her as a mentor, teacher, leader. She will guide you, challenge you and leave you asking for more.”  - Billy Polson, Founder and Owner of DIAKADI Fitness Performance Life in San Francisco

  • “You pushed me. You taught me. You inspired me. And you hurt me. In a good way. I think all of your clients are insanely lucky.”  - Q (San Francisco)

  • “You are the best! So many trainers lose interest in their clients' form, etc. after a few weeks. You were always bringing the A game!” - C. Grabenstein (NYC)

  • “Leaving the gym sweaty after a great workout knowing it was a better workout than I would have done on my own or in a group class. It’s been great to learn new skills I can add into my own workouts. Hurting a little bit the next day felt pretty great too! I really looked forward to seeing her every week. I knew that in that hour I’d get a great workout doing exercises that I would never do on my own. Throughout my time with Tiffany my strength improved significantly and she helped me work through a hamstring injury. In addition to the physical help Tiffany was a wonderful nutrition resource. From sharing new favorite recipes to analyzing my husband’s eating habits, the knowledge she shared with me has been a huge benefit.”  -L.Z. (NYC)

  • “When I first came to Tiffany I was very out of shape due to a serious knee injury. She assured me that we would get my knee stronger and in better condition than before. She wasn't kidding! Today my knee is in perfect shape and I just ran my first marathon since my injury. I always looked forward to my training sessions with Tiffany. No matter how I felt when I entered the gym, I always had a great workout and left feeling very accomplished!”  - P. K. (San Francisco)

  • “Tiffany is quite a taskmaster, but in a nice way. I really enjoyed working with her AND she delivered results!  With a mixture of diet and exercise I lost around 20 pounds in 3 months. I feel stronger and more knowledgeable about the importance of weight training when it comes to maintaining a healthy weight. I was always impressed that so much strength could exist inside such a cute little package. Very inspiring.”  - T. Forsberg (San Francisco)

  • “Tiffany has a great positive attitude and she has a beautiful balance between supportive and firm. You feel like you have to finish even the exercises you don’t like because you completely trust her judgement that you need to do them. She is very knowledgeable and creative so you never get bored.”  - C.H. (Los Angeles)​

  • “Tiffany is trustworthy. I was training towards a specific goal, getting stronger & fitter and realizing, hey, I can actually do this....What’s not to enjoy about getting results.”  - C. Smith (San Francisco)

  • “When I think of Tiffany as a trainer, here’s what comes to mind: innovative, good listener, methodical (but in a good way), bright, and attentive. Oh, and knowledge hungry. She’s consistently pursuing another way to better her clients; and from what I can tell, her clients really reap the benefits. - Andrew Duffy, Personal Trainer (San Francisco)

You can’t make a commitment unless you accept that it’s a choice you make again and again and again.  - Leap Of Faith
