I have used Mariusz Athletix’s personal training app since the lockdown in Vietnam started. I have enjoyed using it very much. It’s not just an app you pay and follow a standard template to work with. Mariusz looked at the limited equipment I have at home and my condition (my weak left shoulder), and he customized a program for me. The results are obvious. I feel my body is stronger, and the best is to keep me sane in this lockdown time.
Anytime I have a question, I can just drop a message to him, and he will respond to my question with a good explanation.
I would say why his app works so well is not just how easy to navigate through it, but also the person running the app behind it.
