Douglas Chironno, Personal Trainer, Registered Dietitian and Exercise Nutritionist M.S.
Douglas Chironno is one of a small number of professionals in New York City who holds both a Master’s degree in Nutrition and Exercise Sciences and active credentials as a Registered Dietitian Nutritionist (RDN) and ACE Certified Personal Trainer. This dual expertise means that when you work with Doug, your training and your nutrition are built together by the same clinically trained professional around your specific physiology, schedule, and goals. Doug’s education is paired with over a decade of full time experience as well as personally competing and coaching clients in powerlifting, men's physique and even prepping models to drop hip size for the runway. Doug’s advanced knowledge in providing exercise techniques and nutrition guidelines will help you improve your posture, strength, muscle definition, weight loss and sports performance with a science based and holistic approach.
Doug has spent over a decade training professionals, executives, and high-performing individuals throughout Manhattan. His approach is evidence-based, precise, and built around long-term results — not quick fixes.
Credentials & Education
Douglas holds the following credentials:
- M.S., Nutrition and Exercise Sciences
- Registered Dietitian Nutritionist (RDN), Academy of Nutrition and Dietetics
- ACE Certified Personal Trainer
- Human Movement Specialist, Brookbush Institute
Doug’s clinical training includes a dietetic internship with Sodexo, where he provided nutrition programming at a Level 1 trauma center and delivered employee wellness education at Weil Gotshal & Manges LLP — one of the world’s foremost law firms.

Professional Experience
Doug began his career as one of Equinox’s top-tier personal trainers while completing his graduate degree — one of the most rigorous training environments in the industry. Since then he has built an independent practice in Manhattan focused exclusively on professionals who take their health as seriously as their career.
Doug currently serves as a nutrition educator at two Manhattan community centers — the Weinberg Center and the Sirovich Center for Balanced Living where he designs and delivers ongoing nutrition education programming.
Doug has also applied his expertise in the fashion and modeling industry, developing a proprietary training system for runway and editorial talent that blends performance training, posture, and aesthetic conditioning. This work led to the creation of Haut-Ties®, a patent-pending wearable resistance accessory he developed and uses in his practice.
As a competitive athlete, Doug has placed in multiple powerlifting meets and competed at three National Level NPC bodybuilding and men’s physique championships — giving him a personal understanding of what disciplined, goal-oriented training actually demands.
