Denise Thomas

Denise has been with Reebok CrossFit ONE since its inception in 2010. In 2012, she spent a year overseas as our Reebok CrossFit Ambassador, consulting and developing Reebok flagship gyms. Over the last 15 years, Denise has been no stranger to travel, earning herself the nickname ‘Gypsy’ from traveling the world as an International soccer player, and as a CrossFit Level 4 flowmaster for the CFHQ Seminar Training Department. Denise brings a lot of experience, passion and smiles to Reebok with her British ways. Since finding CrossFit in 2008, she has competed at both the CrossFit Regional & Games level, and has experienced life on the other side of the barbell, as a CrossFit Games Head Judge in years 2011 – 2017. She loves seeing people demand more of themselves and achieving things they never knew possible – both in the gym and at life. On her travels, teaching CrossFit to the masses and representing Reebok, Denise shares her most powerful observation:

“I have taught CrossFit in over 20 countries and one thing never changes – the message. Coach Glassman’s message never changes. Regardless of the language, the country, or the people in it, the message always stays the same. CrossFit changes lives, and fit people make the world a better place. It is an honor to be a part of this extraordinary group of people that genuinely care about each other…and who like to run, lift and throw stuff around. It’s brilliant! Most fun ever!”
