Prior to Cain Velasquez losing his heavyweight title to Fabricio Werdum at UFC 188 in June, American Kickboxing Academy's Javier Mendez had some concerns about the altitude in Mexico City.
Werdum moved his entire training camp to Mexico to spend five weeks acclimating to the high altitude. Velasquez arrived just two weeks before fight night.
"I told Cain we needed to come down early to get used to the altitude," Mendez said during the first episode of the UFC 188 Embedded series. "He said, 'No.' He's trained here before and he's fine.
