TESTIMONIALS
Aaron Carpenter
Professional Rugby Player - Rugby Canada
I worked with David Thomas, when he was one of the strength and conditioning coaches at Cornish Pirates Rugby Club. I have respect for David as a knowledgeable, approachable and goal driven coach who is willing to work with the players in order to accomplish shared goals. I found that David’s background in power lifting gave him the perfect base of knowledge to guide me to improve my own lifting techniques. He also has the ability to push players to be stronger and fitter within the team environment.

Stan Ahumada
Professional Boxer
I worked with David to reach peak strength. I've always wanted to know how strong I could possibly get with proper training and technique. David has so much knowledge that I felt confident getting into movements that would normally scare me. I box professionally and with David guiding me through my strength & conditioning, I feel that potential is unlimited. Thank you David.
Hugh O'Neill
Professional Football Player - Edmonton Eskimos
I worked with David for my off-season training and found his programs were a perfect fit for my goals. He was able to work with me and adapt to my specific needs. I found David’s knowledge base exceptional and got the results I wanted from my training to go back to the regular season stronger, healthier and more confident in my body’s ability to perform. I would highly recommend David to anyone looking for a professional and approachable strength and conditioning coach.

ABOUT ME
Grym means power in the Welsh language. My name is David Thomas, as a Welsh man living in Canada I thought it appropriate to name the company something tied to my roots. I began working with athletes in 2011 as a strength coach and since then have gained a degree in Sport & Exercise science and competed internationally in powerlifting on several occasions. Working with childrens teams through to serving Army members and old age pensioners.
