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 12 athletes per 1 coach to maintain the quality of the instruction & training.

Results!

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."

TRACKING!

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.

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!"

Clinic Cancellation & Refunds

What is the cancellation & refund policy?

We do not allow cancellations or refunds for the clinics. We strongly suggest that parents confer with athletes before registering them. If athletes can't make the clinic, due to injury or illness, they will receive a credit for the cost of the clinic registration fee that they can use withhin one year from the date of purchase. The credit will allow them to register/attend a clinic on a different date or location.

Injury - in some cases we will provide a refund in documented injuries with physicians note.

 

Can I switch to a different clinic?

Yes, contact Kelly@powercore360.com to submit your request. If a space is open in the preferred clinic, we will transfer you.

Clinic Sessions

There are often 2 sessions per location (one for the morning and one for afternoon). Can my athlete come to the morning on one day and the afternoon on the other?

No, athletes will register for either the morning or the afternoon session for the clinic. They need to come to the sessions they registered for. If your athlete comes at the wrong session they will be directed to come back at the correct session they registered for.

Clinic Format & Coaches

Can you give me more information about the clinic and coaches?

Clinic Format - the clinic is typically divided into two separate 4-hour segments on two separate days. Each 4-hour segment is both physically & mentally challenging. The clinic will focus on three primary areas of instruction: 1) developing power hitting mechanics, 2) related strength development and 3) an attacker's mindset.

Note -we do not hit balls for 8-hours straight, the clinic provides information, education and instruction in exercises & drills. Athletes will be both on and off the court. They will need break times for physical rest & recovery and they will need to bring ample supplies of healthy snacks and water to recover as they break.

Coaches - our coaches come from a diverse background of various related backgrounds including: former players, physical therapists, strength coaches, teachers & volleyball coaches. Coaches are chosen to be PC360 coaches based on many factors but the #1 factor is their desire to improve athlete hitting performance. PC360 coaches are trained to deliver PC360 training methods, drills & exercises. While some were great players or coaches, their #1 role at the clinic is help the athletes and parents learn how to quickly and safely increase their arm speed and power hitting abilities.

Clinic Equipment

What equipment is included in the 8-Hour Clinic Registration Fee?

For 2025 clinics, the following Clinic Pack equipment is included:

  • 1 Hip harness
  • 1 Arm/leg cuff
  • 1 Grey band (very light)
  • 1 Black band (light)
  • 1 Exercise handle
  • 1 Anchor strap
  • 1 Carry bag

 

How do I measure and submit sizing for PC360 training equipment?

When you register for the clinic you will be provided with information on how to measure your athlete's size for the hip & torso harnesses.

 

Will the clinic equipment be shipped to my house?

No, the majority of the time the equipment is shipped directly to the clinic and will be given out there.

 

Does my athlete keep the equipment after the clinic?

Yes, each athlete should train with the equipment after they leave the clinic to improve the mechanics, strength & injury prevention exercises instructed at the clinic.

Arm Speed - Home Program

What is the Advanced Arm Speed Program?

PC360 has developed a 8-week advanced arm speed program to improve volleyball arm speed and power hitting.

 

How does the Arm Speed Program work?

Athletes who register for a 2025 8-Hour Power Hitting Clinic will receive 2 months FREE to the program (to be started soon after the clinic).

 

Is there additional equipment required for the Advanced Arm Speed Program?

Yes, athletes who want to participate in the Advanced Arm Speed Program will need to purchase a PC360 torso harness & an orange band (medium resistance band).

 

Why is additional equipment needed?

The PC360 hip harness the athletes recieve at the clinic will help them hit harder by strengthening the muscles that turn the hips, to increase arm speed and hitting power. The Advanced Arm Speed Program also uses the PC360 torso harness that is worn over the rib cage. The torso harness strengthens the muscles that turn the spine, which increases arm speed & hitting power more than just turning the hips alone.

The two resistance bands (grey & black) that are provided at the clinic will strengthen the muscles around the hips and shoulders to increase arm speed and hitting power. In time, as athletes perform the arm speed program they will get stronger and will need a heavier level of resistance to strengthen the muscles around the hips and spine. Thr orange band will provide a greater level of resistance and greater strength for athletes as they train in the program and build greater strength.

 

How does my athlete get access to the advanced arm speed program?

Equipment - After each clinic is over, PC360 will send parents an email with a registration link for the program. Parents will purchase the additional equipment (torso harness & orange band) and PC360 will ship the equipment to the customer.

Program Access - Once the parent has completed the program purchase link they will automatically receive an email with a link to access the program. It may end up in your email junk folder so you can search your junk folder for noreply@skool.com and you should find the invite to join the program.

 

When can the athlete start the program?

Athletes can start the program when they are ready. Once they have purchased the PC360 torso harness & orange band, they will receive their equipment within a few days. The athlete can start the program without the torso harness & orange band if they are ready to get started.
