Covid - 19 Precautions

Our clinics are always low athlete to coach ratios and during Covid-19 this is no different. Currently we will only be taking 10 athletes per live training session and the athletes will be split in to smaller groups across multiple courts to remain safely spread apart. Athletes and coaches are required to wear masks at all times!

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 keep our athlete numbers low and coach numbers high, usually 1 coach per every 4-6 athletes.

"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.

"Your program was truly a game changer. 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."




We gather data for every athlete at our INTRO CLINICS, so athletes have a baseline at the beginning and can compare how they have the progressed in just 90 minutes of training.

For those athletes that continue on to one of our multi-training programs, we continue on with gathering data and tailoring programs and training to guarantee progress


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!"


How It Works!

Step 1 - Attend Introductory 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 their hitting mechanics.

Then we teach the basics of:

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

We introduce them some of our proprietary 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. 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.
