He fixed all the forms I thought I was doing it right. Fixed the tightness/pain on my legs that was affecting some movements. It was like getting a physical therapy session too, crazy! Plus he's genuine, professional and always happy. I live in a different state and I really wish there's a "find a personal trainer like Wes" search option! read less

He is such a versatile and flexible trainer who is willing to hear you out on whatever fitness goals you have. For me, I had the goal of deadlifting over 135lbs last year and felt like it was impossible. Wes helped me out with my deadlift form and made sure I got the right biomechanics down with each movement. Because of Wes's sharp and keen eye, my deadlift form became pristine in which i was able to deadlift over 200lbs within a span of 3-4 months.
Wes is definitely full of wisdom and knowledge and will answer questions to the best of his ability from what he's learned. He's definitely an honest guy who will help you, not only fitness related things, but will definitely give good conversations about anything! read less

When he first came to Wesley, he had no idea on how to get into lifting, he could barely lift the bar on the bench press. Wesley taught him a vast array of exercises and went all nine yards making sure his form was immaculate. He is vastly more confident in his ability to lift and more motivated about fitness than ever before. I would highly recommend Wesley for any fitness goal you wish to accomplish. read less

He knows what he is doing. He gives you insight on what each movement does on your body. I learned so much from him.

He really understands physiology and body mechanics and uses this knowledge to optimize your training routine and regimen. I appreciate that he tracks actual metrics and numbers to make sure you are on track to reach your goals. I'm always impressed at how observant he is when watching form. He always seems to pick up on tiny details in how I'm performing exercises and uses this to improve form and identify other areas for improvement. I highly recommend training with Wes! read less

The first time we worked out was awesome! He explained every workout as we went along as well as proper form and the science behind the workout. He helped me add 40 pounds to my deadlift by tweaking just my form alone. Wesley has alot of experience in personal training as shown in his approach in the gym. Overall, Rule Fitness. read less

He has a vast amount of knowledge on proper form and biomechanics. He analyzed my posture and noticed that I had an anterior pelvic tilt and helped identify what I was doing wrong that might be causing the issue. He helped me address the issue with a variety of stretches and exercises that I still use to this day. After training with Wes, I now have a better understanding of biomechanics which influences all of the exercises I do. My squat and deadlift form is damn near perfect now. I would highly recommend him to anyone because the educational aspect of what he does is invaluable. read less

Whether you're a beginner or a veteran in the fitness world, Wes can definitely elevate your workouts into a more enjoyable and effective experience. read less

Once I started training with him, I was opened up to a whole new world of health and fitness. Yes I had been working out and eating more consciously but I quickly learned that both my diet and workouts were sub par. Working out on my own, I had picked up poor posture and form that hindered my advancement. Without understanding the makings of a healthy diet, I was actually just going through cycles of starving myself then overeating. When I started training with Wes, all of that changed. He helped me to gain better eating habits and fixed my form so that I could lift heavier, run faster, and jump higher. Wes helped me to reset my negative mindset and started showing me that I am capable of doing everything. I also appreciated that even when I fell of course he never judged me but instead helped me to get back on track. I am so thankful to him for instilling good habits in me to help me continue improving myself. Training with Wes has given me great results, losing 20+ lbs and going from a size 12 to 6. Lastly and most importantly, at a recent doctor's visit my doctor complimented me on my improved health, my BMI had gone from overweight to normal and all my labs were great. I know I would could not have gotten these results without help. I can't recommend Wes enough, you must train with him! read less

I was diagnosed about as a teenager with a disease of the connective tissue, and doctors had been telling me for years that I'd always be weak and grossly underweight. I've had multiple surgeries on my lungs, developed asthma and respiratory problems, and had significant joint issues that made exercising seem impossible.
When Wes began training me a few years ago, I was 6' tall and just 108 lbs, and fresh off another lung surgery. I had no idea what I was doing, but he went above and beyond to design routines and adapt exercises for my physical limitations, progressively tailored them as I went from beginner to regular gym-goer, designed a diet for me, and introduced me to supplements, and taught me to love fitness. Within just the first few months, I had already gained over 30 lbs in muscle. Today I'm a solid 160 lbs and my doctors are STILL shocked by the transformation nobody thought could ever happen. I'm happier and healthier than I've ever been, and I seriously owe it all to Wes. read less
