Welterweight Rory (Ares) MacDonald and middleweight Francois Carmont were on their best behaviour, serving as benign training partners as top coach Firas Zahabi gave Humphries an introduction to mixed martial arts paces before a small crowd at a Quebec City mall.
It was all part of the UFC Experience, a public workout ahead of Wednesday's Ultimate Fighter Nations Finale UFC card.
Under the tutelage of Zahabi, Humphries worked on a double-leg takedown, armbar and kimura submissions as well as punching and kicking. At the end of the session, he had her put all the moves together in taking the pro fighters to the ground and then going after a submission.
The 28-year-old from Calgary clearly enjoyed the lesson, enthusiastically throwing a tattooed tree-trunk of a leg over the six-foot-three Carmont in a bid to subdue him as he lay on his back.
MacDonald is ranked the No. 2 contender in the world at 170 pounds by the UFC while Carmont is No. 9 at 185 pounds. Zahabi trains both in Montreal as well as former welterweight champion Georges St-Pierre.
The bobsled champ signed autographs and, holding her two Olympic gold medals, posed with fans before changing into workout gear to get some tips from Zahabi, along with a local youngster.
"One more," Zahabi yelled as Humphries kicked the training pad he was holding. "Harder."
As he urged her on to kick again and again and again, the coach mischievously asked if she was competing in the next Olympics. When she said yes, he told her: "You've got to do more," referring to the kicks.
"Come on, you've got four years. Go. Again. Again. Four years of this."
The inspiration worked. Humphries kept kicking, with the audible thuds becoming louder.
"Didn't want it to end," she tweeted later.
Humphries is a longtime fan of MMA — so much so that she planned to fly back to Calgary on Sunday night to honour a previous commitment before returning to the Quebec capital to take in the fights.
"It's so cool for me to be able to see and get to meet the fighters and be a part of something so spectacular," she said in an interview. "It's an opportunity you can't miss, so you make travel work."
The UFC treated her like royalty, producing a real championship belt that she put on while holding her medals with an Olympic-sized grin.
Humphries says the UFC is literally part of her family. Her parents named their cats Rampage and Tito after former light-heavyweight champions Quinton (Rampage) Jackson and Tito (The People's Champion) Ortiz.
But combat sports are new to the bobsled champion, who only has one boxing class under her belt. She is, however, contemplating adding MMA training as part of her general fitness regimen.
While not bobsled specific, the explosive nature of MMA could be beneficial, she said.
So what about getting punched, she was asked?
"I think it's something I can handle. Bobsleigh's not exactly the most princecessy of sports," she replied. "I'm used to rough and tough a little bit and I can take a punch."
Then she paused.
"I've never actually been hit so I can't actually say that," she said with a giggle.
Humphries cited Jackson and current women's bantamweight champion (Rowdy) Ronda Rousey as her favourite fighters. Rousey, the UFC's first female title-holder, is a former Olympic bronze medallist in judo.
"Nowadays women can do anything the men can do," said Humphries, who won her Olympic gold in Sochi, Russia with Heather Moyse, who also competes in cycling and rugby.
"At the end of the day, women are inspirational in completely different ways than men," she added. "And to know there are women out there that are as rough and as tough, and can dedicate their lives and work just as hard, it (the UFC) allows us to show that off to the rest of the world.
"I'm super-proud of all the women that do sports across the board, especially at such a high and extreme level. It's an inspiration for me and I know many young girls out there."
Don't look to Humphries to start fighting for real, however.
The UFC women's competition is restricted to bantamweight (135 pounds), although a new strawweight division (115 pounds) is being formed.
"I'm far away from that," she laughed. "As of right now I would definitely be one of the heavyweights, for sure.
"I usually compete at around 170, I'm about 165 right about now. So I'm a long way off from a 115 or a 135. But at the same time, our training and the way we train with our sport, we need to be at that weight so I do what I can to maintain my weight up there."
Wednesday will be Humphries' first live UFC show.
"It's one of those experiences that I've never had that I'm very, very excited to see."Suggest a correction
