A new coaching experience

No more guessing or worrying

Look, I can empathize with how intimidating trying to get in shape can be. Between the constant battle of not knowing what you should eat and how much of it, or what exercises you should be doing to best align with your goals. At 3G Fit, I remove the guesswork and complexity. I'm here to show you how to adhere to a healthier lifestyle and promote consistency, rather than jumping from one fad diet to another. We're in this for the long game and you should be too. Book a call with me to hear how I can help you along your journey to a better you.

Get Started

Meet your trainer

Cornell grew up in Richmond, Virginia where he learned his true passion for sports, personal training, strength and conditioning, and most importantly - his love for the gym! Cornell is a former D1 football player who attended James Madison University - Go Dukes! During his tenure at JMU, Cornell aided his team in winning the 2018 National Championship and understands what it’s like to win at the highest level! With that- he is able to translate his football mindset from the field to the gym when working side by side with his clients. He has over two years of experience as a NASM Certified Personal Trainer, while also becoming a certified expert in his field.

At the conclusion of Cornell’s football career, he decided it was time for a lifestyle change, leading him to transform his body from the inside out- by working hard, determination, and consistency. His true passion is to help others transform their lifestyle, body, and mindset. It is Cornell’s personal mission to help you become the BEST version of yourself. At 3G FIT, we are in this together, and we will be with you every step of your journey!
