Donal studied medicine and immunology in Zurich and holds a doctorate in each discipline. He is also a Gracie Jiu-Jitsu purple belt and an instructor for children and adult classes at the Jiu-Jitsu Academy Zürich.
Donal has been lifting weights in some form for over 15 years and has focused on barbell training for the past 7. He is especially interested in promoting the benefits of resistance training for those that are least likely to engage in it spontaneously. With the support and encouragement from friends and family he set up the MiniGym in 2020 in the hope of building a community of like-minded people that want to get or remain strong and enjoy barbell training.
