That whole training system is a scam. Those treadmills and chambers looks very special but they are useless. Yesterday Garcia was bad, and his stamina against SD wasn’t better at all as before.
Golovkin, Pacquiao, Khabib, Tony Ferguson. Just 4 fighter who were training on high altitude all their life. All 4 has/had brutal gas tank.
Out of how many others? Look at the science behind it. It’s basic Biology. Calzaghe never trained at altitude and he had a phenomenal engine. “Baby Bull” had the best engine in the game when all the boxers you mentioned were active, yet he only trained at sea level. Look at GGG and Manny now. They rent stopping anybody.
