If you think a workout must feel sore or painful to make you fit, try Essentrics.

A happy you requires a balanced body, and that’s the goal of our workout. Betty Ng - a NASM Certified Personal Trainer and the only Fully Certified Essentrics instructor in NYC - helps you achieve this by guiding you to move with a purpose, to explore and understand how your body works, and to feel and function at your best at any age. 

Through balancing weak and strong muscles, through loosening and conditioning your fascia (connective tissues), you will unlock tight or even painful joints to enjoy a greater range of motion. You will move with greater ease, speed and power, and your body will become stronger and more flexible at the same time. Your balance as well as your posture will improve, while your brain-body connection will strengthen.

Are you looking to tone and slenderize your physique? Are you suffering from chronic pain or recovering from accidents and surgery? Are you looking to relieve pain and stiffness? Or to improve your athletic performance? Regardless of your goal, you will enjoy the fun and motivating workouts with Betty. 


Essentrics is also known as "Classical Stretch" on American Public Television. Using physiotherapy techniques, it is a pioneering anti-aging workout that strengthens and lengthens from head to toe through continuous, rotational movements at moderate speed. Unlike many methods that focus on only muscles and bones, Essentrics also conditions our joints and fascia (connective tissues). With quick, visible results, Essentrics leaves you toned, pain-free, balanced, and energized. Great for men and women of all ages and all levels.


Is Essentrics a type of yoga? No. Essentrics is about movements and dynamic stretching, not poses. Essentrics is also secular and focuses on the tangible: brain-body instead of mind-body connection.

Is Essentrics a type of barre workout? Some Essentrics routines have barre/chair work. Unlike many barre workouts, however, Essentrics does not use external weights and concentric movements which shorten muscles. (Example: lifting dumbbells.) Instead, it uses the eccentric technique of strengthening in lengthened positions, using our own body weight as resistance. This eccentric technique soothes and conditions our joints while sculpting lean, toned muscles. 

Who can do Essentrics? The workout is for men and women of all ages and levels, whether you are a couch potato, weekend warrior, or professional athlete. You can also do it if you are pregnant, suffering from chronic pain, or recovering from a surgery or illness, as long as you have doctor's approval to exercise.
