Sports Performance Training in Kansas City

All three of our kids have worked with Greg and David at AYC. Having a workout tailored to their needs was invaluable in helping them accomplish their goals, whether it’s making the high school team, or playing professional sports. Of course, your child will only get as much out of training as they put into it, and AYC will help them realize their potential.” – Jenny Wentz

“David’s sessions are tough and productive. They yield results from the start. More importantly, our son enjoys going!! The location is super convenient so homework time isn’t wasted commuting. We think the workout techniques learned at AYC can be used well in college and beyond.” – Donita Miller

“My son had just turned 13 and wanted to increase his strength and flexibility, mostly with hope of improving his baseball skills. Working David had a significant impact on Dom’s physical strength, and has also given him a boost in self-confidence! He looks forward to his sessions at AYC, and clearly sees the benefit in his overall fitness. It has been a pleasure to get to know David and experience his genuine excitement at helping Dom achieve his goals.” – Julie Zanone

Jake Randa started training with AYC shortly after the 2015 football season ended. During that time, he’s toned his body, increased his speed, and improved his cardiovascular endurance.

After helping lead the Shawnee Mission East Lancers to the 2016 state baseball title, Jake graduated the following year while collecting the 2017 Preseason KS 6A Player of the Year, 1st Team All-State, and 1st Team All-Conference honors in the process.

He is currently a scholarship athlete at Northwest Florida State University.

Emma Jarrell started training with AYC in June of 2017, although she first met David wayyy back in 2005 because her dad coached him on the varsity baseball team at Shawnee Mission East.

During Emma’s tenure on the soccer team at Shawnee Mission South, she earned 1st Team All-State honors in 2016, 2nd Team All-State honors in 2017, and 1st Team All-Conference honors both years.

She is currently a scholarship athlete at the University of Central Missouri.

Henry Miller started training with AYC in November of 2014 during his sophomore year of high school. Since then, he’s completed 250+ sessions, gained approximately 40 pounds of muscle, and added 7-10 MPH to his fastball.

After helping lead the Shawnee Mission East Lancers to the 2016 state baseball title, Henry graduated the following year while collecting 1st Team All-State and 1st Team All-Conference honors in the process.

He is currently a scholarship athlete at Xavier University.
