Train the Load and Release
Cory describes Polar Grip as a sequencing and stability tool. The hands pull gently away from each other against the fixed opposing knobs. This hand load creates a physical reference for stability in the upper spine and shoulders.
Timing Matters More Than Force
The feel is early, controlled tension—not squeezing harder at launch. Release the tension as the body rotates. Polar Grip complements the hand awareness and barrel control trained with the original Split Grip Trainer.
Put it to work
A simple progression.
- Place the hands against their respective knobs.
- Begin with gentle opposing pressure on a tee.
- Learn when to release before adding ball flight.
Load the hands with control. Release the tension into the swing.
Use the ball type approved for your model. Start with controlled work and choose a bat suited to the hitter’s size and strength.
