About

My name is Viktor Genov, a Calisthenics Personal Trainer of 10 years, the name and face behind Tough Muscles, a title I came up with 9 years ago for an Instagram handle, although it was not for another year that I actually started using that account and posting content on social media!

Fast forward to 2025, Tough Muscles is an extraordinary part of improving people's quality of life worldwide, both in person, in London, UK and online, providing expert coaching, nutritional guidance and ongoing support to men and women alike through personal training, bespoke training programmes and workshops, as well as creating the opportunity for all men to go above and beyond when exercising, thanks to Tough Muscles Premium Comfort Men's Activewear - from exceptional softness of Bamboo Briefs, Socks and Tops to incredible ease of movement and sturdiness of high quality Nylon Shorts, I am honoured to know that my existence plays an important part in contributing to society and makes a difference for the better!
