Experienced tutor in Personal trainer in Washington, Cornelius offers private lessons tailored to your needs.

Yoko really knows his stuff, and is a great fitness instructor. He's always on time (seriously, he's never late for a class), and did an amazing job of designing a fitness regimen that fit my goals.

I'm in average shape, 31 years old, and a total newbie to working out at gyms. Yoko really helped me get started with free weights and kettlebells, and greatly improved my form and focus while exercising. I also have a few old sports injuries (ankle and shoulder), that Yoko was able to take into account to safely build muscle and prevent re-injury.

Regardless if you're an established gym bro or more of a gym newbie like me, I highly recommend working with Yoko.

I’ve trained with Cornelius several times now — for a while in 2017 and again recently to get myself out of a pandemic funk. In both instances, I set out to improve my strength and endurance, and hopefully lose a bit of fat along the way. I’ve been seeing him 2x week since May and have seen significant improvement in endurance, and I’ve lost about 12 pounds without significant lifestyle changes otherwise. He’s so great about monitoring my form and ensures his clients can meet their goals during his sessions and also at the gym on their own. He knows how to push me and incorporates high-intensity exercises like boxing among high strength-training routines, which I really appreciate. I’ve recommended him to friends and will continue to do so!

I have been training with Cornelius for several years now. He is a fantastic trainer. He manages to squeeze a great deal of exercise into each workout routine hitting on all the key areas, including cardio. At the same time, he incorporates new exercises/machines frequently to keep it interesting. He is also very attentive to details to ensure to avoid any injury. He was always very accommodating to my frequent work travel (prior to COVID) which made it easy to train with him. I wholeheartedly recommend him to anyone regardless of the fitness level and goals as he will adjust the workouts accordingly to accommodate each person’s needs.

Cornelius has been an amazing trainer. He’s extremely attentive especially when working with injuries. The knowledge he has shows in each of his sessions. He’s always on time and prepared. I never leave feeling like I could have done more. I just extended my sessions because I’ve been seeing so much progress already. Highly recommend!

Cornelius is a fantastic trainer. He knows exactly how much to push me without over doing it. He also comes up with creative and interesting workouts every week so I am never bored and always challenged. I am significantly stronger than I was 2.5 years ago when I first started working with him and I'm excited to see what future workouts will be.

I’ve worked with Coach Corn for a few years. He not only got me in shape, but he got me to love working out. He set an amazing foundation for me. When I’m away, he checks on me to make sure I’m not falling off. Coach Corn not only cares about your physical fitness, he’s invested in your mental and emotional fitness as well. What more could you ask for????

Cornelius has me doing things I never thought I could do - I feel stronger, more confident, more at ease in my body. Coming off of lockdown I thought I would struggle to feel myself again. With consistency, intentional pushing, and a dash of humor, I have gotten stronger than ever and actually find working out kind of fun! All alongside learning the craft of boxing — which is empowering, challenging, and the best workout. Cornelius knows what’s up. He’s knowledgeable and makes it happen. Could not recommend more!

Knowledge, flexibility in exercises, and constantly moving using your whole hour (you definitely get what you pay for).

His flexibility with my work schedule. Great personality! Demonstrates the proper technique for the exercises.

Cornelious is very professional, knowledgeable and cares about his clients. I have grown stronger and leaner since working with him. Every workout is different so I feel challenged.

I began working out with Cornelius around five years ago, after a running injury and a slow recovery had forced me to take a different approach to fitness. My physical therapist recommended resistance training, and I began training with Cornelius to rebuild my core strength and flexibility.
Cornelius is incredibly reliable, consistent, and always encouraging. He is a stickler for technique, resists fitness "fads", and helps me focus on the basics while mixing in enough variety to keep me challenged and interested. I've picked up boxing under his instruction, which has been a huge bonus for my cardio, agility and for stress relief!
Over the years, he has seen me through marathons, a wedding, new jobs and life challenges, as well as a pregnancy and post-partum recovery. I am stronger and healthier because of him.

Libfitness has truly helped to transform my body and essentially my life. Cornelius Yoko is by far the best athletic trainer I have ever had. My time with him during my initial consultation would foretell how detailed he is and how committed he is to creating a very unique program made just for you. Not every trainer emphasizes correct form when guiding your workout, but he does this consistently. He will remind you that the body moves the way we want it to move and it will only do that when we learn how to control it. His workouts are innovative and challenging. Tell him your goals and he will get you there. I have already invested 3 years of hard work with Libfitness and plan to invest so many more.

I have worked out with other trainers before and Cornelius far exceeds all of them. I had been a physically active person most of my life. Then I had surgery a few years ago and remained inactive for about a year as I recovered. By then, I had gotten out of shape, lost stamina, gained weight, and feared that I would injure myself. I was afraid to walk into a gym. I had to admit I needed help. And that is when I found Cornelius. I was basically starting all over again with my fitness routine. My goals were to lose weight, build strength, improve my cardio, become toned, and rebuild my confidence. Cornelius listened and then worked with me to develop a fitness plan that would help me achieve my goals. He has been encouraging every step of the way. He maintains a balance of pushing me to do more than I thought I could ever do and being understanding of my limitations. Each session, it's a different workout so it doesn't get boring or routine and he also explains the purpose of each exercise. He customizes each session based on each client's needs. He gives his complete attention during the workout sessions. I've been working out with Cornelius for quite some time and not only have I seen a major improvement in my physical fitness but also my overall well-being. His workouts have also helped me with my daily living, whether it be carrying heavy luggage in the airport for work travel, running the bases during an office softball game, walking up several flights of stairs with groceries, or shoveling a driveway filled with heavy snow and not feeling sore after. Cornelius of Libfitness LLC is a trainer who has your best interest at heart, listens and develops a fitness plan based on your goals, and helps you reach those goals.
