Shane Tusup isn't one to keep a low profile, no matter the stage.

That was him on Saturday night on the first day of swimming in the Rio Olympics, the muscular, man-bunned dude in a t-shirt and shorts, jumping, stomping, screaming, cheering, encouraging and generally causing a scene while his pupil blew the doors off the competition. 

That pupil _ Hungary's Katinka Hosszu _ also happens to be his wife.

Tusup's intense demeanor toward Hosszu at the pool has caused some in the swimming community to raise their eyebrows, but Hosszu sings his praises over and over again, both for the improvement she says he has brought in her swimming and the connection they have as husband and wife.

The couple reached the pinnacle on Saturday night when Hosszu shattered the world record in the 400-meter individual medley to win gold.

It was the culmination of a risky plan that Hosszu first broached with Tusup while the two were dating in 2012 after a disappointing performance in the London Olympics.

"I felt a lot of pressure going into London and I was super nervous before the final," said Hosszu, who finished fourth. "I remember not enjoying it. I just wanted it to be over. I was, I guess more scared. I was afraid of what happens if I don't win.

"After I started working with Shane, we just decided we're going to keep racing and keep improving and have fun."

She credits Tusup for instilling the confidence in her. And as demanding and brusque as he can be, the couple clearly still have no problem finding time to have fun.

"At the end of the day it's just swimming," Hosszu said afterward. "It's something that drives me and it was an amazing experience to share this moment with someone I love."

She looked to the back of the press conference room after completing that sentence and gave sent a warm smile in that direction for Tusup, who was watching quietly, for a change.
