Hi I'm Marcus Reuben, Your Personal Trainer. I'm a British trainer based in the heart of Paris and have been successfully helping people achieve their personal fitness goals since 2005. I'd love to tell you that I was the fastest man on the earth by the time I was 20, I have a PHD in Nutrition and I was Mr Universe three times by the time I turned 30, but unfortunately I can't. Just like most of you I've made some mistakes in fitness and listened to the wrong advice. The good thing is that I made these mistakes years ago so you don't have to.
