Will Celis


I’m William Celis and I am an NFPT certified personal trainer with over 20 years of experience. I’ve won bodybuilding championships from 1994 to 2013 and in 2017 I was the Ontario Classic Physique champion.

I live my life by two mottos:

  1. Practice what you preach – I live the same healthy lifestyle of good nutrition and regular exercise that I also motivate my clients to follow.
  2. Quality over quantity − Train smart! It’s not about how much you lift, or how often, or how much time you spend in the gym. It’s about how you do it!

Join the Sweat Shoppe mailing list to keep up to date and motivated around the most effective fitness programs available anywhere.



“I started working with Will in preparation for Masters World Championships of Brazilian Jiu Jitsu 2016. To make the lightweight division I needed special attention to my diet, and to maintain and increase my strength.

Will took me on and coached me through a deep weight cut and managed all of my strength training needs. I have never met anyone that can match Will’s knowledge, skills and sensitivity in guiding me through this process.

It was one of the most difficult things ive ever done and Will was with me every step. He was right there when the weight felt impossible to lose while customizing my strength training to match my body’s needs and the needs of my sport. Will is a rock of compassion and encouragement. Trust the process!”

-Jason Brandt, World Master Jiu Jitsu Champion

“I am lucky enough to do bootcamp classes at The Sweat Shoppe. One of my favourite classes is Thursday lunchtime with William Celis. Every Thursday at 12:15 it is leg day. William always has a well planned 30 minutes for us.

He concentrates on the legs but the arms and abs get attention also. I leave totally spent… many calories burned and totally pumped. William’s classes are hard and fun! His music choices totally make the 30 minutes fly.

His encouragement is contagious. He is helpful and mindful with his adjustments. I try to never miss a class.”

-Judy Land, Bootcamper

“In March of 2017, I competed in the OPA regionals in the Bikini Short category. I dedicated myself to study and understand the muscles of my body, did my own food plan and also my workouts. The competition became my thesis and I passed it by winning 3rd place at the Regionals.

After that my new goal was to compete at the Provincials. I did not know anything about it and without guidance, out of 25 people who competed that day, I got #25 (That’s right, the last) but not all was sadness.

There, I met my coach William whom I contacted 3 months before my last chance to compete in the last Provincials of 2017. Thanks to his knowledge and all my dedication, I won 2nd place! Now we have the intention of going for the 1st place at the Nationals.

Thanks William, without you it would have been difficult to achieve it”

“I had 16 weeks to get ready for my very first competition. Even though the last 8 weeks were the toughest mentally, I finished really strong and I was indeed in the best condition of my life at the end. I’m honestly not sure I would have survived those last few weeks if we hadn’t been working together. Not only did my new diet make my life bearable, but he was also around any time I had questions or concerns and was always extremely reassuring with his responses.

He’s great at communicating and even better at making sure I am personally getting everything I need out of the program. He’s been flexible when I’ve had challenges and I honestly couldn’t be happier. He’s an amazing coach, and he knows his stuff. I highly recommend William to anyone preparing to compete or even just looking for some guidance on getting into better physical condition. Not only are his nutrition recommendations on point, but his training plans are KILLER.

Thanks again William, can not wait to do it all over again!”
