About Lez Stelmachowski

Hi there, I am Lez. I am an endurance coach, entrepreneur and youtuber. This website is the home of my life’s work.


Lez (Ironlez) Stelmachowski has earned the reputation as a seasoned Personal Trainer in Edinburgh’s fitness space. Growing up, his interest in fitness and sports piqued early on in his life. However, what further fueled his passion was his parents’ unwavering support.

Currently, Lez is the Co-Founder of Fitness Soul along with his partner in love and business, Joanna. Together, they are 110% dedicated to helping people make all of their fitness goals a reality. Ultimately, he is on a mission to empower his clients to harness their infinite potential so they can pave the path to lasting success. Most recently, he has been working on launching the Fitness Soul Podcast. 3 times Ironman Finisher, he is now training for the Celtman Triathlon 2019.

Furthermore, Leszek holds an MSc in Physical Education and various other designations, including Ironman Certified Coach, Precision Nutrition Level 1, Personal Trainer Level 3, IKFF kettlebell coach, British Weight Lifting Coach, and CrossFit L1Coach. He is also a member of the prestigious UKSCA (UK Strength &Conditioning Association).

When he isn’t training, Lez enjoys cycling, swimming, and running. He also loves painting, networking, and reading self-development books. Above all, he is a life lover and an avid student of life.
