Both founder and coach at CrossFit 559, Jerry Stump is one of the many who has benefited from CrossFit.At the age of 46, Jerry is able to do things that he was not able to do in his 20’s.Flexibility, strength, agility, and coordination are just a few things that CrossFit have help Jerry with.
Prior to being introduced to CrossFit, Jerry weighed 275 pounds. His athletic background revolved around extreme sports such as bungee jumping, skydiving, snowboarding, skiing, and motocross. Over the years he acquired numerous injuries which he used as an excuse for his extreme weight gain.
In late 2009 Jerry’s daughter and husband who are avid CrossFitters introduced the sport to him. With all of the positive feedback and proof of how CrossFit changed their health, Jerry decided to give it a try. After his first workout, he was HOOKED. Jerry found himself getting the same adrenalin rush that he once did from the various extreme sports he was active in.
Today, Jerry is in the best shape of his life and can do things now that he thought were unrealistic for someone with the injuries he experienced.
Jerry’s passion for CrossFit began in late 2009 when he converted his garage into a CrossFit gym and started training with friends and family. The dream kicked into high gear in 2011 when he received his Level 1 CrossFit Cert. It continues today in 2012 as he sets forth to open the doors at CrossFit559 and share his passion and dream with athletes of all levels in the 559 community.


Coach Mike Thurston began his crossfit career in May 2012 here at Crossfit 559. While never playing high school sports Mike had become more of an occupational athlete while serving as a soldier for the US army. His deployments to Iraq and Kosovo had taught him the physicality of real life and the need to be prepared for what life threw at him. While serving Mike had always loved intense lifting sessions but had yearning for something more. It wasn't until after working for the fire department and EMS Mike stumbled upon Crossfit 559 with a friend. After his first workout destroyed him he became like so many others and was addicted.the constant variety and intensity of Crossfit workouts quenched his thirst for challenge. He still continues to serve his Community and his Country and attributes Crossfit for his success. His love for coaching and the success for his athletes is what drives him to work hard as a coach.

I am a second generation Firefighter and currently a Grad school student at CSUB. I began Crossfit by trying it alone at my local global gym in Valencia Ca, without a coach. But It didn't take much for me to realize that Crossfit is a life changing experience. And I hope to ride this love for fitness and health as long as I can. I took my Level-1 Certificate course at Crossfit Monrovia and I have completed other Specialty trainer courses.
