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 maximum to maintain the quality of the instruction & training.

"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."

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.

"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!"

Step 1 - Attend Introductory 3-Hour Clinic

Our 3-Hour Introductory Clinics are the foundation of our training programs.

In these clinics we use the latest technology to measure each athlete's hitting velocity (arm speed) and slow motion video analysis software to capture hitting mechanics.


The first hour is a ZOOM virtual session at home (off-the-court) facilitated by PC360 Master Coaches), where we provide video analysis of:

  • Ideal power hitting mechanics & technique
  • Introduce ideal arm swing body rotation mechanics for power hitting
  • Discuss the athletes' "why" and provide knowledge so athletes & parents understand the learning & training process
  • Provide an overview of what college coaches are looking for physically & mentally on the court


The second and third hours are on-the-court with local PC360 Certified Power Hitting Coaches, introducing the athletes to the basics of how to move their body to improve:

  • power hitting mechanics
  • arm speed
  • hip turn & whole-body rotation
  • injury prevention techniques and exercises to prevent knee, back & shoulder injuries

PC360 Training Equipment

We introduce some of our proprietary PC360 training products to speed their learning and make immediate improvements in their power hitting mechanics and actual arm & ball speed.

At the conclusion of each clinic we have everything we need to help the athlete build a plan to improve their hitting performance in follow-up training sessions. They will leave with an understanding of the training process and what they need to do to improve their power hitting performance.

Step 2 - Follow-Up Training

Once the athlete has attended an Introductory Clinic, they are truly ready to take their performance to the next level.

Depending on location, we offer numerous monthly training opportunities, where athletes can continue to train with us many times per month and throughout the year.

Depending on the option chosen, we offer the option to track each athlete's power hitting training data (hitting velocity, hitting mechanics and power hitting confidence). This way you'll know your hard earned money is actually making a difference.
