If you want to know what my developing session is like with my bro, watch this.
This is my first meeting with my bro, today's bb coach, @chetorture. He is kind of violent delivering nonstop heavy punches on my fully swollen balls, but I take them bravely and no safe word for manning myself up! Mandarin conversation recorded and subtitled in English.
This is a complete and effective training video. Although there is a warm-up, today's coach seems to like starting with great force, getting stronger and stronger with continuous minutes in each round! However, I performed very well, without calling to stop, today my little stones have become stronger again!
This kind of complete training assisted by others can be done at most once a week, 3 times a month allows especially fast progress, after the balls are swollen it's more effective, but you have to be a bit of a tough guy like me to endure it!
