Experience and qualifications
Authentic feedback from competitive athletes and recreational trainees. No marketing filter.
Marcin and I have been working together for over a year. Initially I thought boxing would just be a bit of fun. But Marcin takes it seriously! Every session is precisely planned and he never lets up for a moment, all in a friendly atmosphere. Marcin is a true professional who is passionate about what he does.
