Siro was born in Italy and moved to London when he was a kid at the age of 5. He has always been into sport and physical activity from a young age, taking part in various football tournaments and playing sports casually on a regular basis. In 2014, he graduated from university successfully completing his Graphic Design course which led him to build an effective video editing business from home.

Further down the line he decided to pursue his passion for fitness and began studying for his level 2 & 3 (Fitness Instructor & Personal Trainer) qualification which saw him land a role as a Fitness Coach in a commercial gym. There he picked up a wealth of experience, teaching over eight different types of fitness classes as well as successfully starting up his Personal Training business.
