What do we know of Sanchez's training and conditioning? This man didn't look beat after going 15 rounds with Nelson or 8 with Gomez. Unbelievable
He conditioned himself the Mexican way at altitude and good old fashioned hard work, sparring, callistetics and sparring. He was always running the hills and mountains where he lived. He had a Dr Valenzuela who worked with him and on his stamina. Dr Valenzuela was an early S&C coach. Sanchez had savy old school guys who were open to new ideas and would bring in private doctors to camp to ck the fighters heart rate something they do now. The best Mexican trainers, Cuyo Hernandez, Lupe Sanchez, Nacho Beristain, Pancho Rosales, Cristobal Rosas, Romulo Quiarte, all used private doctors, sports medicine guys. If I am not mistaken even before the '60's, there was a doctor ready to ck the heartrate of the fighters.
I'm no Sanchez expert, but I remember a pre-fight vignette where he was running in the desert in a sweatsuit (and yet didn't seem to be sweating at all) and they talked about how unusual his heart rate recovery was. I think it might have been the ABC prefight before the Patrick Ford fight. They said Sanchez's heart rate returned to normal rate in less than a minute and how this was completely unusual. I thought he was an amazing athlete with off-the-charts stamina.
