Collection: Swing Dynamics

Buy the 4-Bat Set. Get the App, Instructional Videos & Swing Efficiency System — Included.

The complete Swing Dynamics 4-Bat System — $600. Every set unlocks Rob Crews' full training library, instructional videos, Swing Efficiency System, and Pre-Game Warm-Up — all delivered in-app.

Rob Crews' overload/underload training system. Four Custom Pro Maple wood bats that organically reprogram your movement patterns — so your body self-corrects swing flaws automatically. Built on 20+ years of coaching elite hitters.

Each bat trains one specific element of the swing:

• Perro Grande — Overload Bat. Heavier than standard. Develops strength, power, and kinetic chain engagement at the point of contact.
• The Shorty — Short Bat. Trains connectivity. Keeps the barrel locked to the body through contact.
• May Street — Underload Bat. Lighter than standard. Sharpens barrel speed, swing path, and bat-to-ball timing.
• Ridiculous — Long Bat. The longest bat. Forces the body into correct sequencing — lower half leads, torso follows, hands and barrel fire last.

Used in every lesson Rob teaches. Available for baseball and softball/fastpitch.
