SecunderCustomer from 🇩🇪Brilliant
It's not just about the exercises but understanding the 'why' behind them. This book has been a game changer for me.
Aisyah RoziCustomer from 🇦🇺Great for a beginner
As a complete beginner, at first I was overwhelmed. But this book guided me through the basics in a very structured way. It's perfect for anyone starting out.
Ralf WiegandCustomer from 🇩🇪The Power of Mr. Yellow
I like the anatomical yellow man and he was the main reason I bought the book. His illustrations make understanding the exercises and their effects on the body much easier.
