After Conor McGregor lost to Nate Diaz at UFC 196, the Irishman became obsessed with cardio training.
The training seemed to pay off, as McGregor went five rounds with Diaz in the rematch at UFC 202, beating the ultra-distance runner via majority decision.
McGregor has carried that ethos into his headlining bout at UFC 205, which will see the featherweight champion challenge Eddie Alvarez for the lightweight belt at Madison Square Garden.
Alvarez, though, who captured the 155-pound title at UFC Fight Night 90, believes McGregor’s strenuous cardio program is a waste of time.
