Let's Be Honest!

If you have been to most youth sports programs, you might notice that they just jam pack as many athletes in the session as possible, with little focus on individual instruction. More times than not, athletes leave with no clear idea of what they need to be doing to improve "THEIR" game. That's what makes a Powercore 360 clinic different. We purposefully keep our athlete numbers low and coach numbers high, usually 1 coach per every 3-5 athletes. Powercore 360 sessions are all about making the athletes better, faster but also about continued education and training after the training is over.

"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!" Parent

"Your program was truly a game changer for Whit AND for me.
You provided a reasonable and achievable road map for all of the boys to become the best athletes they can be. They’ve never received this kind of information before and within 4 hours I guarantee all of them saw drastic improvements in their skills." Parent

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. We would highly recommend Billy’s programs, and hope to have him back in Jackson Hole soon. Club Director
