About

Serious Inquiries Only I appreciate you taking time to view my profile and consider me as your trainer, I hope I’ll be the one to guide you to your fitness goals. My name is Sim Williams and I’m a Certified Personal Trainer and Strength Coach serving Philadelphia. I’ve been an advocate for everything fitness for as long as I can remember which is why I created Koa Performance (named after my son). My goal is to help driven adults train like athletes while building strength, endurance and managing weight loss. I have over a decade of experience of one-on-one and small group training, with a background in boxing, powerlifting, distance running and Army physical fitness, just to name a few. I feel what separates me from most trainers, is not my multiple certification and accolades, but my true passion to spread the importance of health and fitness. I can’t wait to meet you and help you achieve the results you deserve!

Sim is a great trainer and beyond that a positive and solid guy. He knows that bodies cannot be built without the right mindset so he brings that into the floor as much as a routine. He has been a great trainer and has designed programs with my goals in mind. He also focuses a lot on fundamentals and teaches you the value of those than just merely lifting. He makes u work hard but have fun along the way!

Having Sims as my PT has really changed my perspective on weight loss. He’s been my PT for a little over 3 months now and I am on track to lose the weight that I need in order to get to my goal weight. I know it will be a journey but I can already see and feel a difference. We focus on strength training, HIIT workouts, and a few other workouts tailored to my needs and physical agility. So far I have kept the weight off, which was very hard to do on my own. He pushes me to do my best and feel confident. He’s very respectable, patient, keeps you accountable with your eating and fitness goals. I can always go into every workout knowing that I am going to get a great workout in and hit my goals. He makes it fun and most importantly each workout is tailored to my strengths. A year ago, I thought I would never be able to run again with my injuries, but now I don’t even feel any pain while I workout. I feel much stronger and I always look forward to each session. I am definitely recommending him to all my friends and coworkers!!!! He is definitely a trainer you want to have for long term goals, whether it’s to get stronger or lose weight and just to train. Thank you Sims!!!
