TESTIMONIALS FROM PRO ATHLETES

Started at 12th Round Fit in January 2020 following my 4th NFL season. I was looking for a conditioning alternative after struggling to maintain weight. What I found was so much more, not only did I get in great shape, I've played my best ball since. Marty and the squad do an incredible job of creating a family atmosphere but also holding you accountable to your own goals. I am forever grateful to have walked in the gym on a Tuesday morning in Scottsdale.  Since that day, it's been part of my daily and off-season routine not only to box but to learn life lessons from the wisdom of Marty and Pete.  I look forward to every off-season from here on out being spent at 12th Round Fit where I become limitless.

I'm thankful to Marty and 12th Round Fit for providing a space for competitive athletes and retired competitive athletes to come together to train, teach, and tussle!

12th Round Fit has been a great spot to train the past three years during NFL off-season.  Marty and his staff are a unique group.  Not only does boxing get you in the best shape possible, Marty's staff teaches you the actual sport of boxing.  He challenges me every time I come into the gym and I always walk out feeling like I got better.

Marty and staff at 12th Round Fit assisted and contributed to my overall goals to condition, tone, and strengthen my body in the off-season.  They exceeded my expectations and I couldn't be happier with my results and experience.
