Meet Our Team
David Castillo
Born and raised in Miami, FL, I've dedicated my life to serving others and helping them reach their full potential. With a BA in Criminology and experience in both the Navy and law enforcement, I've developed a strong foundation in discipline, leadership, and problem-solving.
Now, I'm passionate about using my skills to empower individuals through fitness and nutrition. As the founder of IDYL FIT, I offer personalized online training programs designed to help clients achieve their goals and live healthier, happier lives.
Beyond physical fitness, I'm committed to providing life coaching and support. My belief in the power of personal growth drives me to help others overcome challenges and unlock their true potential. While family and home are my anchor, the gym is my sanctuary.
​As a certified NASM-CPT with over 5 years of experience, I'm passionate about helping people achieve their fitness goals. Inspired by my military boot camp experience in 2008, I've embraced fitness as a lifelong lifestyle. I specialize in strength and conditioning, and weight loss management, and I offer personalized training programs tailored to individual needs. My goal is to create a supportive and motivating environment where clients can reach their full potential.
