  • Avi Kothari

    At the age of 15, amidst the COVID-19 pandemic, Avi Kothari's true fitness journey began. What started as a hobby soon became a lifestyle, and within a month, he was hooked. Avi immersed himself in CrossFit and functional movement training at Interchange, laying the foundation for his passion for fitness.

    Over the past three years, Avi has immersed himself in the world of bodybuilding, working closely with IFBB pro and former Mr. USA, Nick Trigili. Under Trigili's guidance, Avi has gained invaluable knowledge on hypertrophy training, fat loss, and gut health. He is on track to turn pro by the end of his college journey in 2026 and looks forward to competing throughout his twenties.

    Avi's dedication to fitness led him to a role as a sales representative at Vitamin Adventure, a local supplement store. This experience deepened his understanding of nutritional supplementation and its impact on fitness outcomes. Furthermore, during a paid summer internship at Protein Research, a nutraceutical and dietary supplement company located in Livermore, CA, Avi acquired valuable insight into the manufacturing process for health supplements.

    Coach Avi believes in taking a holistic approach to fitness, ensuring his clients remain at peak health while achieving their physical goals. With a focus on gut health, weight training, hormone regulation, and nutrition, he provides comprehensive guidance for optimal results.
