Ryan Heerman â Boston College Baseball
Ryan came in ready to work. Since starting at PSP: exit velo up from 92 to 103 mph, his 60 down from 7.5 to 6.7 (laser-timed), squat from 335 to 460 lbs, plus 20 lbs of good weight added along the way.
Ryan shows continuously he has what it takes to play Division 1 college baseball. Keep working dude. A lot left in the tank.
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.

CJ Herrick â RWU Baseball
CJ came in unsatisfied with where he was at. He trained hard for consecutive years, got a s**t ton stronger, added 30lbs of mass, increasing his exit velo by 20 MPH. Thats what consistently does for consecutive years. Wild.
CJâs a completely different athlete than the day he walked in the door. And the crazy thing is heâs nowhere close to his ceiling. Keep working dude. Proud of you!
Most athletes have no idea how much performance theyâre leaving on the table simply because theyâve never gotten truly strong.
There is an absurd amount of performance you can pull out of simply becoming brutally strong at a lot of things.
If youâre a 150-pound high school athlete worried about getting âtoo strong,â donât be silly. Youâre years away from that problem.
Dedicate this off-season to getting truly strong and youâll thank me later.
P.S. To the coaches out there preaching âdiminishing returnsâ to high school or college athletes, youâre just doing it wrong.
Out-Train. Out-Perform.
+200lbs on his squat in 2 years.
Max DeRoche hits a 30lb PR at 475 the week before he heads into year 1 at UMass Lowell Baseball .
Guys are working while youâre taking a month off.
Max will be a dawg for Lowell.

Some Batcave OGâs with the next generation.
Grateful for this crew and what theyâve brought to PSP over the years đŚđŚ
He lost 46 lbs of grip strength in his throwing hand in five weeks.
The season started, and he stopped training.
Senior pitcher. Tested mid-March going into his season. Tested again five weeks after he stopped lifting. 46 pounds gone off the throwing hand.
He never felt it. Thatâs the problem.
Grip isnât a party trick. Itâs one of the ways we track strength and capacity in the throwing arm.
Seasonâs over. If the last four months were games, tournaments and showcases and training took a back seat â youâre not the same athlete you were in March.
Donât assume you are.
Find out.
What held? What slipped? Whatâs limiting you next spring?
Thatâs why we test. The Initial Performance Evaluation gives you a real number to start from and a plan built off it.
That pitcher retests next week. Heâll know exactly where he stands.
Youâve got months. Donât guess with them.
Measure it. Build the plan. Attack it.

Itâs easier to get ahead than it is to catch up.
The â28s & â29s hit some PRs this week.
Stack enough weeks like this and you become a different athlete.

Heavy lifting does not make baseball players stiff or slow.
Bad programming does.
Athletes become stiff and slow when strength is the only quality being trainedâand everything else gets ignored.
A 2023 systematic review and meta-analysis of 55 studies found resistance training improved range of motion. The improvements were not significantly different from stretching.
Another 2023 systematic review in baseball found resistance-based training produced significantly better throwing-velocity results than control conditions in 8 of the 12 studies that reported between-group comparisons.
Heavy lifting is not the problem.
Incomplete programming is.
At PSP, our athletes lift heavy.
They also sprint, jump, throw, rotate, decelerate, move fast, and train through full ranges of motion.
We are not training athletes to become powerlifters.
We use the weight room to build better athletes.
Strength is not the problem.
One-dimensional programming is.

7.5 â 6.7. +11 mph EV. Undersized to ACC commit in 14 months.
Ryan Heerman committed to Boston College Baseball today.
Everybody sees the edit, but what they donât see is the work Ryan put in to get there.
Ryan started at PSP in June 2025.
He was already a good baseball player with real tools.
He was also undersized.
His starting numbers showed the physical gap:
â 7.5-second laser-timed 60
â 92 mph max exit velocity in BP
â 335-pound squat
Ryan needed to add size, get stronger, and get faster.
And we needed to develop all three without allowing one to come at the expense of another.
Thatâs the part most people get wrong. Add weight without adding force and you just end up with a bigger, slower kid.
We measured where he was, built his program around what was limiting him, and trained strength, speed, and power together throughout the year.
Then Ryan executed.
For the next 14 months, he drove more than 40 minutes each way to PSP four days per week.
He followed through outside the gym. He ate enough to add more than 20 pounds. He stayed in the lab. I know there were plenty of nights he stayed hitting with Boston Prime owner Jack McLaughlin until 11 p.m.
This morning, on the day of his official visit to BC, Ryan asked to come in before we opened so he could get his lift in with me before heading to campus.
This afternoon, he announced his commitment.
By July 2026:
â 6.7-second laser-timed 60 at college camps
â 103 mph max exit velocity in BP
â 460-pound squat
â +20 pounds of bodyweight
Ryan was an undersized, good ball player with big goals. He knew he could do something about it and went and did it.
The commitment is the headline. The work is the story.
Proud of you, Ryan. Congratulations to the entire Heerman family.
