Marwin, who was recruited due to his work at HarborCenter's Impact Fitness, has been known to inject his own personal flavor into this role.

That was when the combine relocated to Buffalo's HarborCenter in 2015, and local pro Brazilian jiu-jitsu fighter Jordan Marwin joined the staff that administers the bike tests during fitness day.

At least it has been since 2015.

Except if you attend the NHL Combine. In that case, hearing these phrases shouted boisterously is an annual rite of passage.

If someone were to overhear these phrases with zero clue as to what they were listening to, they may suppose they just stumbled upon an unruly band of middle school vandals.

"I think about what I would want to motivate me during the tests," Marwin said. "I've done the Wingate several times in grad school and it's a miserable process. A lot of these kids I don't think they're used to pushing themselves hard 'off' of the ice. So I kind of look to boost their energy, boost their morale and give them a little of my energy during the test."

For the most part, the combine is a quieter, and professional atmosphere. Fitness testing isn't open to the public, either, with only team hockey operations staffs and media permitted to enter.

The one exception to these businesslike surroundings is Marwin, who every time a prospect takes the bike test, is overheard by pretty much everyone in the arena.

In a recent letter he wrote to prospects attending the NHL Combine for VegasGoldenKnights.com, Reid Duke cited the #bikeguys, saying he remembers being so dialed in that he never heard them when he was on the bike.

Although Duke's visit to the combine in 2014 predates its move to HarborCenter, making his insight into the awareness prospects have of Marwin obsolete.

So we asked the U.S. National Team Development Program defenseman David Farrance, A 2017 draft eligible prospect, about Marwin.

"You know that he's there," Forrance. "You definitely hear him. I actually kind of like it. It gets me focused and ready to go, so I don't mind it.

"It's totally on the fly," Marwin added. "It's in the moment. When I talk to them beforehand, I try to get a feeling for their personality and I match what I say to their personality.

"I just try not to be too passionate and curse because it's on camera. So I try to find little fillers like that. Say things like 'break this bike' or 'rip it.' Just things that are very destructive-that's what I find motivation in myself."

Enthralled by Marwin energy - and stunned that he maintained his pace for nine straight hours without losing his voice-we have decided to compile a list of his best motivational one-liners.

Here are a few that were used at this year's combine that stood out to us:

BREAK THIS BIKE!

EMPTY OUT THE TANK!
