About MoveFit

Chaityn “Chay” Isaacson-Brewster is an LA-based personal trainer and professional dancer with a UC Irvine dance degree. Trained in ballet, modern, jazz, and contemporary dance, she has worked with artists including Ray J, Jake Miller, and international performers.

After overcoming foot injuries, Chay became a NASM-certified personal trainer, combining her dance expertise with strength, mobility, and holistic fitness coaching. This led to the creation of MoveFit.

At MoveFit, we focus on the whole person—workouts, nutrition, sleep, stress, and mindset—helping you build habits that create lasting strength, confidence, and well-being. Every program is personalized to fit your goals and lifestyle.

Whether you want accountability, guidance, or simply to feel stronger and more confident, MoveFit helps you move better and live healthier—both in and out of the gym.
