Every Journey Starts With Science, Not Guesswork.
Train smarter, move faster, and reduce injury risk inside Bradenton’s only sports performance lab.
Mike Venus, ATP Tennis
“Niels is an example of a consummate professional. Each workout is different and pushes you beyond what you believe you can achieve. His knowledge of body dynamics and his motivation is a major factor on where I am today.”
-Andrey Rublev, ATP Tennis
“Yes, it was amazing work for me and it helps me a lot. I got much stronger in a short period of time and of course I would like to work more when I am in Florida.”
Fabrice Martin, ATP Tennis
“I did my first pre season with Niels for 2 weeks just before starting my 2016 tennis season. The first 3 days were really really tough and painful but Neils got me through it and starting the second week I knew his workouts will make a big difference into my movement and physical conditioning. It didn’t take long to see the first results as I went from #75ATP to #37ATP in less than 5 months
I just keep on doing his workouts as much I can on the road and as soon as I have some time off I go to Bradenton and come work out at Fit Crew. Andrew helped me out on my diet and I lost a dozen pounds and 3% body fat in 10 days just by following his diet and working out with Neils .
I just wish I could have them on the road with me all year long .”

As your personal trainer in Bradenton, we’ll use these results to create your performance blueprint: identifying where you’re strong, where you’re vulnerable, and how to reduce injury risk while boosting performance.
