The 8
Adjustments
Know what every move does to the ball. Then make it by the amount you called.
Coach Roger Petrin · 3x Southwest PBA Champion · Former NCAA Div 1 Bowling Coach · USBC Silver Certified Coach
Most bowlers own two moves.
When the lane changes, they reach for the same two answers every time. Those two are not wrong. They are two tools out of eight.
This workshop fills the toolbox. You learn all eight adjustments, sorted by which way each one moves the ball, and you learn to call the move and the amount before you step up.
Three directions, eight moves
The question on the lane is always the same: does the ball need to read sooner or later, or cover more or fewer boards? Every adjustment answers one of those, or both.
When the ball reads. Breakpoint closer or farther.

The decision
The Thinking Box and the Film Room Challenge.
Real Film Room clips throughout, with a mirrored version of every right-handed clip so left-handers read it from their own side.
Every adjustment is trained the same five ways
- 1
Benchmark
Ten shots at your normal. The average is home base.
- 2
A little more
One step up from your benchmark.
- 3
A little less
One step down from your benchmark.
- 4
Call it
Say the move and the amount before you step up.
- 5
Check it
Well executed? Did it do what you called?
Steps 1 to 3 build your range. Steps 4 and 5 build trust: when the move you call is the move that shows up, you can commit to it under pressure.
Notes you wrote. A bag you mapped. Two moves to train.
Your filled notes PDF
Six pages: the map, the method, every adjustment card, your bag, the Challenge log and your trust check. Filled in by you, yours to keep.
Your bag, with a job for every ball
Benchmark, heavy oil, step-down, control, angular, spare. You find out which roles you already cover before you buy anything.
A way to decide after a leave
The Thinking Box and the Film Room Challenge: read the leave, name the direction, pick the smallest move.
Your first two to train
Two adjustments from your "not yet" column, each with a benchmark, a step size, and how you will know the move showed up.
Knowing it vs. owning it.
Built for bowlers. Better with a parent beside them.
Competitive bowlers
Youth and college bowlers, about 13 to 22, who compete and want more answers on the lane than feet and ball. Right and left-handed.
Parents
Sit in as your bowler's Challenge partner. You learn the same language they use, so the talk after a block is about the read, not the score.
Coaches
A shared map for your players, with step sizes and a log you can keep using at practice.

Call it. Then own it.

Before you register
Do I need to be at the lanes?
No. This is a classroom workshop with video. Bring your notes PDF open on a laptop or tablet. You take the five-step method to the lanes afterward.
I'm left-handed. Will this work for me?
Yes. Every right-handed clip has a mirrored version, and each adjustment includes the left-handed cue.
Should a parent attend?
We recommend it. Parents make great Challenge partners, and the last part of the workshop is a conversation with families about next steps.
What if my bowler already has a coach?
Good. The map and the five-step method give your home coach a shared language and a log to work from.
Will there be a recording?
No. This is a live, virtual workshop. An summarized transcript will be provide to those that attend.
What is your refund policy?
Refunds are available up to 24 hours in advance by contacting Roger Petrin at Roger@MyMindsetGear.com
Call it.
Then own it.
Know what every move does to the ball, and leave with the two you will train first.
