Here's the short translation (I'm keeping the same structure but summing up what I don't think is crucial for understanding)
During his long rehab, GSP got more than enough time for a brainstorming.
Even tho temporarily disabled, a true champion never stops thinking of ways to improve (description of GSP reign over the WW division)
So long before he could start training again, GSP decided that it was a good time for a few changes. His apparent unability to finish his opponents has been extensively documented, which is why GSP decided to give a particular attention to his boxing training.
When his rehab was finally over, by the end of last june, GSP didn't go for his usual gym in montreal, rather, he went to the Claude-Robillard center, next to the track where he use to go train his athleticism, where he started training in the sweet science with Stephane Larouche.
One of Quebec's most reputed trainer, trainer of two former world champions would finally start working with one of the most famous canadian athletes ever.
"it's not that things were wrong before, actually I was very comfortable with things being the way they were before, but I still decided to take on the opportunity to change my routine, there is absolutely no bad blood with anyone"
" to me, boxing is very important. In MMA, you really can't di without so I decided to step up my game in that area. Stephane's experience will really make a difference on my training"
A transformed athlete
well before he brought Lucian Bute to glory, at a time when GSP was not yet an international superstar, Larouche was already following GSP's career. back when purists and old school boxing enthusiasts did not consider MMA as a real sport, one of the most respected trainers was already amazed and fascinated for that young and talented canadian athlete (GSP)
"he used to come and spar with us every now and then. I knew he was into combat sports but I don't remember if he was yet in the UFC. All I can say is that I was impressed by his heart and courage. He didn't want anything to be half baked, he wasn't the best, he wasn't dominant in any way, but he always came back to train the next day, he wasn't giving up" remembers Larouche.
GSP's career quickly took off and drove him away from Larouche's gym. The coach was never far and was always availaible whenver George had a question or enquiry about anything specific. The relationship remained on a friendly level and was never really professional. George being one of his former student, Larouche was still following his career closely.
"When GSP fought Fitch (august 2008), I remember being amazed by the athlete he became, I couldn't believe that this was the same guy who came by at the gym only a few years ago, I was really impressed"
Improving strength by technique
Today, Larouche is getting an accomplished athlete. Although he has been facing psychological challenges coming from the long layoff and a quick return to the highest level of competition, George should, in theory, at 31yo, only begin to reach his prime years.
GSP's already a high level athlete with well established routines, so no major change should be expected in his training philosophy.
"I have a very precise role to play here. Georges asked me to help him improve his boxing, and that's what he pays me for (the text doesn't actually refer to money here). My goal is not to change everything and anything in his training and his game, that would only induce doubt in his mind.
Rather, I'd want his hands to be even faster, his movement to be smoother, this is my goal. Make his moves smooth, relaxed and then explosive at the end, these are the fundamentals of boxing"
All while being invested in boxing for the most part, Larouche is well aware of the criticism on St-Pierre's unability to finish despite his absolute domination inside the octagon. (the rest of the paragraph details the criticism and their impact on GSP's popularity, we all know them here I assume)
"If tense, no athlete can reproduce what he learned in training when he steps in a ring or a cage. The goal here is to be relaxed and the best way to improve the punching power at this level is by improving the technique. A better technique equals a better speed, a better speed equals a higher potential in punching power. Georges is exceptionally physically strong, if we succeed in adding speed to his movement, he could get extremely powerfull" says Larouche
"Stephane is an exceptionnal teacher. He really teaches me Boxing's science and many things I had no idea about. I improved my punching power, timing and footwork. I can't wait to see how it will fare in the octagon"
But the wait was very long. 18 months after his last event, GSP is now preparing for his big come back, november 17th at Bell Center, Montreal, where he will attempt to claim his belt back from Carlos Condit, the current Welterweight interim champion
Because Condit's style is close to muay thai and kickboxing, ST Pierre and Larouche did not focus too much on technical details so far. The coach gives directions and oversees the training camp, also bringing in the appropriate sparring partners.
the new coach's implication goes beyond the octagon.
"Stephane is an intellectual, a boxing genius! On video, he's able to see the very small detail that even I can't see. He made me understand a lot, he made me sees opening that I would otherwise have missed by miles"
But Larouche quickly gives the compliment back.
"George is really a very hard worker, he really doesn't mind suffering in the gym, which is why I'm very happy and I think we're making a great team"
alright, I tried to translate the important points, left out some small details.
