Eddy Reynoso explained that he was very firm in his first conversation with former unified heavyweight champion Andy Ruiz.

Earlier this month, it was made official that Reynoso had agreed to become the new head trainer of Ruiz.

In June 2019, Ruiz pulled off a massive upset when he dropped Anthony Joshua four times to secure a seven round stoppage to capture the WBO, WBA, IBF, IBO heavyweight titles at Madison Square Garden in New York City.

But after that win, Ruiz partied for two months and then started his training camp late for the December rematch with Joshua.

Ruiz was in poor shape when he entered the ring, which allowed Joshua to easily outbox him over twelve rounds for the win.

A few weeks after that loss, Ruiz parted ways with head trainer Manny Robles.

Ruiz's former trainers, like Robles and Abel Sanchez, were highly critical of heavyweight's work ethic. They both claim Ruiz can be very difficult to handle when he's not fully focused.

Because of Ruiz's past issues with staying in the gym, Reynoso made a few things very clear to him when they initially discussed the scenario of working together. 

"I was really blunt. I like working with boxers who have discipline. I don't like wasting time. I didn't like losing when I didn't have my current level or a certain prestige and right now I have something to protect... something that cost me to get to where I am. I like working with disciplined people," Reynoso stated in a video interview with Box Azteca.

"The only thing I asked him to do was to keep himself disciplined. I don't know if he is an undisciplined boxer because he's already been world champion. I think he can beat whoever he is in with... with a solid preparation combined with a good strategy and discipline. He already proved that he can beat one of the best boxers out there at that weight and I think he can beat anyone."
