Tyson LaRone

Tyson's fitness journey began at a very young age as a competitive swimmer. Training under some of Canada's foremost coaches, he competed all over North America and at one point ranked 2nd in Canada for his age group in the 200m butterfly. At fifteen, he quit swimming and started in Ketto Ryu Ju-Jutsu and Kyokushin Karate. 



Three years later, he started Brazilian Jiu-Jitsu under Mike Yackulic, learned about Agatsu and met Shawn Mozen in Calgary to get his Level 1 certification. He attended the Somatics Institute of Massage Therapy for the next two years to obtain his diploma and worked as an RMT full time for the next two years while building his F.A.S.T. Fitness program, and travelled to Toronto to get his Level 2 certification. He saw in Shawn the same passion for technical mastery and innovation that had driven him to learn about kettlebells in the beginning and was thrilled to be chosen as a Senior AKC and be a part of Canada's gold standard for fitness education. Aside from kettlebell training and BJJ, Tyson is a recreational powerlifter and specializes in periodization and programming using sport science methodology from the former Soviet Union.
