Glen’s journey through strength and conditioning started as a youngster in martial arts. It didn't take long for him to follow his dad into the gym and from the age of fourteen - he was a sponge for information. In 2011 Glen changed careers to follow his passion in this industry.
Since 2011, he’s qualified as a master kettle bell instructor. This is the piece of equipment that Glen believes is key to unlocking someones athletic potential. Aside from the kettle bell qualification, he has also gained diplomas in nutrition, level 3 personal training, posture and pre/post natal training and nutrition.
Glen trains his clients in private sessions as well as with online programs to help people around the world accomplish fitness goals they once thought to be out of reach. The pursuit of excellence in performance is his passion and getting the best out of people is the greatest reward.
