ABOUT ME
Experience and Passion
Hey, I'm William! Since 2017, I have self coached my own bodybuilding journey including 3 successful competition preps. Bodybuilding is my true passion and I have completely dedicated myself to chasing progression and self-researching nonstop over the years, taking no voluntary breaks and allowing nothing to get in my way. Through countless massing and cutting phases, I've transformed myself from a scrawny 115lb distance runner into what you see today. At my recent bodybuilding competition, I competed in both Classic Physique and Men's Physique, winning the Men's Physique Overall title, 1st in Classic Physique Open Class B, and 2nd Overall in the Classic Physique.
Throughout the years I have casually coached and written programs for people around me and since 2022 I have been officially training all kinds of clients both in person and online. I have always been extremely detail oriented and consider any and all factors when it comes to one's progress in bodybuilding and fitness, and with my focus on helping others the past few years, I have further expanded my knowledge and adaptability to cater to clients of all kinds of backgrounds and conditions. When you transform your body, everything else follows — mobility, mindset, longevity. That's not a bonus. That's the point.

TESTIMONIALS

Will might be the smartest person I’ve ever met when it comes to strength training, muscle growth, and nutrition. Not only that, he’s a great teacher and puts an enormous emphasis on form/technique to maximize growth and minimize injuries. He’ll make sure your form is better than everyone else’s, including other personal trainers at the gym. But most importantly, he’s a great person. He’s funny, engaging, and makes the workout a fun experience. I had Will as my trainer for 3 years, and not only did my body have a crazy transformation, but more importantly, my mindset did. Can’t recommend him enough.

I had an incredible experience training here. My PT was extremely knowledgable and always knew which exercises were best suited to my specific goals. What stood out most was the attention to form. The pointers were clear, practical, and made every workout feel more effective and safe. I saw a genuinely impressive transformation in a relatively short amount of time, both in strength and overall fitness. Highly recommend to anyone looking for a trainer who really knows what they're doing and can help you get real results!

I highly recommend training and coaching with Will - he is absolutely Five Star! He is awesome to work with, engaging to talk to, and he transformed my life with the coaching and training we did over a year and a half. His expertise is excellent! He is meticulous in guiding my every exercise to deliver the results I need, and he customized my coaching program to fit my requirements. He helped me FOCUS with intention on every rep for the body-strengthening exercises he guided me on. I no longer have back issues due to the excellent training I've received from Will, and I can do weight-lifting exercises now that have wildly exceeded my expectations. Will also helped me by taking videos of me doing the exercises so that I could learn and improve. Most recently, I trained with him 4 times a week, and it was the most phenomenal experience I've had in training! I strongly encourage anyone to give themselves the golden opportunity of being trained and coached by Will! He is the best!

Will has an incredible eye for body mechanics and could spot the smallest adjustments that made every exercise more effective, challenging, and safe. I was amazed at how one simple cue could completely change how I experienced a movement, and I saw noticeable gains in both strength and muscle definition in a relatively short time. What I appreciated most was his calm, steady confidence. I felt supported and encouraged to safely explore my edge, often discovering I was stronger than I realized. I can’t recommend Will highly enough!

Will is the best! He is very knowledgable and not only told me what exactly I was doing and how my body should be moving but why I was doing it each exercise. He also knew how to be encouraging and push my body's limits without feeling like I was being pressured into anything. I highly recommend him as a personal trainer and exercise specialist!

Working with Will was a transformational experience. He's thorough in his guidance, rigorous in his process, and pushes his clients to achieve excellence. He's also great fun to work out with and enormously resilient to my constant whining! He's a first class professional and first class person.
