Low 80s to 89 mph.
Charlie Crabbe built his entire first year at PSP remotely.
He came to us strong and willing to work his ass off. But he was tense, stiff, and tried to muscle through everything.
More strength alone wasnât the whole answer. Charlie had to learn how to relax, move well, and apply his strength at the right time.
We attacked that with ballistic and overspeed eccentric loading, plyos, collision-based tasks, positional isometrics, and single-joint work at specific ranges.
That work targeted reactive-strength qualities and challenged Charlie to change his movement strategy: reduce unnecessary tension, absorb force efficiently, stabilize key positions, and redirect force quickly.
Less muscling up. Better timing. More usable force.
The results:
Drop jump RSI +44% from March to August.
99th percentile peak force.
93rd percentile relative peak force.
96th percentile rate of force development at 200 milliseconds.
Touching 89 mph on the mound.
Those numbers donât come from effort alone. They come from Charlie consistently executing the right plan.
Now, after a full year remote, heâs finally training with us in-house.
Getting strong matters.
Learning how to use it is what changes performance.
Big shoutout to Nate Espelin and the Boston Prime Baseball team for all the killer work theyâve done with Charlie on the pitching side.
Out-Train. Out-Perform.
