Yeah Mat is a back-to-back CrossFit champion. 
back-to-back a few times. He got into the sport almost accidentally. he was an olympic lifter and competed at crossfit gyms just to win competitions for cash
Yeah he has won the championship 4 times now. Honestly very impressive. 
The stuff he has to do in thos competitions is wild too. They don't necessarily know what the work out will be in advance. One time they did a multi-mile trail run and at the finish line, the Ref told all the racers to turn around and run it in reverse
Yeah it really does take a lot of training to do what he can do. And even between practicing and training for the competition in between he was able to finish and graduate from university, with a double major. 
Ya. he has an engineering degree. Doesn't fit your typical "meat-head" crossfit guy. He broke his back before crossfit when he as training for the US olympic lifting team. 
Yeah two different majors in engineering. He not only got the physical part to him he also has the brains. That’s what probably helps because he has the right mind set. 
Yea his mental game is strong. he didn't train with music because there's no music at competitions. That sounds like a lot of work and no fun. Definitely some mental toughness there
Yes I could never imagine working out to no music that’s what keeps most people motivated as they have a beat to move to. Have you ever actually been to a completion to watch them? 
No. I watched the 2019 and 2020 games online. They are back doing the finals at the university of wisconsin this year. It would be fun to see live. I think the team events at those competitions are impressive. Lots of wild obstacles
