Black Hole Training" is named for its incredible power to transform. Like being pulled into a black hole and coming out the other side, those who complete it return with a new perspective on life. It's the world's hardest training, with 10 intense chapters that push you to the limit. Created by @cherrysin98, also known as a hybrid monk, in the Himalayas when he was just 15 years old, this program was inspired by his deep connection with nature.
