improve your hitting power in first session!

Let's Be Honest!

Most youth sports programs just jam pack as many athletes in the session as possible, with little focus on individual instruction.

We purposefully cap our athlete numbers at 20-30 maximum to maintain the quality of the instruction & training.


We gather data for every athlete at our clinics and compare before & after results

Athletes see an average of 19-27% increase in performance and confidence at our clinics

"Our players finished the program with a renewed sense of competitiveness, a desire to hit harder, and be a bigger impact for their team. As a club, we continue to use the equipment to improve our hitters abilities, and we are seeing great improvements."

Club Director




Sports aren't just about being the best athlete, they're also about believing you're the best athlete.

We not only track performance data, we also track athlete goals, plans and confidence from before the clinic, throughout the entire process.



Goal Setting & Rewards!

Built in to each clinic is our "Biggest Hitter" power hitting competition

Athletes, based on their hitting velocity, receive wrist bands that reward them and set goals for them to reach the 30 MPH, 40 MPH or 50 MPH Club.

Clinic Video Clips

"I can't rave enough about the improvements our daughter made in the 2 days of this program. I think it has made her excited to start working harder on training her body to do what it needs without needing to think about it. Thank you and all of the coaches, for everything you taught her (and me) this weekend!"
