The Trained Fists Foundation

2024-2025
Foundation
The Trained Fists Foundation was established to offer appropriate training to vulnerable residents of The Hague.
Originally founded in 2016, as a private initiative by sensei Willem de Bles (3rd dan in Japanese jiu jitsu, and also an expert in the Chinese kung fu style pak mee pai, taught by Kong Mien Ho). The initiative officially became a foundation by the name of 'De Getrainde Vuisten' in 2024. His pupils John van Maanen, Alex Eerhart, and Ruud Groot became fellow board members.As De Getrainde Vuisten we put our focus on community building, seniors, individuals working their way out of social isolation, people in vulnerable circumstances, and marginalized groups. Community is strength.In the fall of 2025 sensei De Bles decided to fully focus on pak mee pai and other things in life, and left the board. We thank him for everything he taught us. And of course we will use his knowledge as an important base to further our journey. Together with you!
