I’m Juan (Personal Trainer) the founder of JSM Fitness. Based in St Albans & Harpenden, but covering most of Hertfordshire.  I offer one to one mobile and online coaching personal training services with an emphasis on meeting your fitness level and needs both physically and geographically, whenever and wherever you choose.

With over 8 years of experience in the fitness industry as a PT and more than 10 years as a semi-professional gymnast I have always loved pushing my fitness level to the max, keeping myself healthy and fit,  I’m a straight talking, highly motivated and enthusiastic Personal Trainer and I certainly practice what I preach when it comes to my body.  

Before I became a PT, I worked in the financial services industry in London for over 10 years, but fitness, keeping healthy and fit was always my passion.
