UFC welterweight champion Georges St-Pierre hopes he never has to experience the same kind of past year he has gone through again.

St-Pierre, who last fought in early 2011 against Jake Shields, will return from knee surgery next month when he faces Carlos Condit at UFC 154.

The lengthy time on the shelf, though, will not cause any issue to the 31-year-old Canadian, St-Pierre recently told UFC.com.

The hardest part to being out for so long is to be inactive, to be unable to do what you like to do for a living. This will be the biggest challenge of my whole career. I have to fight the toughest opponent I ever fought. I have to come back from a long layoff, a big inactive period of time. I’m not afraid of Carlos Condit. I hope Condit focuses on targeting my knee. It’s not a weak link anymore. There is nothing I can’t do now that I was able to do before.

A noted workout warrior, GSP has been rehabbing for the past several months. He tore his ACL prior to a scheduled bout with Nick Diaz, and the UFC placed Condit in a match with Diaz to determine an interim champion.

St-Pierre is one of the longest reigning UFC champions, and could position himself for a super-fight with Anderson Silva upon getting past Condit.
