Sometimes your biggest limiter isn’t physical. It’s psychological.

Watch us “trick” Ben Scullin into a 12 inch jump PR.

Ben’s fresh off his high school baseball season and jumping around and just under 300 on the triple broad jump. His all-time best is 305 inches.

Between reps, without telling him, and without him seeing, we moved his target two feet further back.

Next rep? 317 inches. A full foot past his PR.

Nothing in his body changed in those 15 seconds. He didn’t get stronger. He didn’t get more explosive. What changed was the limit his brain was defending.

Here’s the principle: your nervous system sets a governor well below your true ceiling. It’s protective by design — but for an athlete, that protective limit is often the thing standing between them and the rep they’re actually capable of.

Part of our job is knowing how to pull every ounce of output out of your training. And it’s a chain reaction: bigger output in training → bigger stimulus → greater adaptation → maximized game performance.

This is the work most programs never touch. We’re not just running you through workouts. This is a training system engineered to pull every last bit of athletic potential out of you — and give you the best possible chance to perform when it counts.

Out-Train. Out-Perform.

655 LB Squat for ANOTHER All-Time Record 🚨

Huge squat from Goose () today to break the PSP all-time squat record with a 655 on the bar.

Massive Test Week so far at the Batcave 🦇

385 for the New PSP All-Time Record. 🚨

— football commit — just put up 385 on the bench, taking down the old house record of 375.

You think you need more work. What you need is a well-designed program.

I’m tired of pitchers being told that lifting heavy will make them slow, tight, or hurt.

— class of ’26 RHP and Bentley commit — came into his PSP offseason up to 87. One offseason of heavy, intelligent training later, he touched 90.7. +3.7 mph.

And he didn’t get slow, tight, or hurt doing it. The testing showed the opposite:

→ Squat: 375 → 465 lbs

→ RFD at 200ms: +91%

→ Med ball shot: 31 → 36 mph

→ 10-yd sprint: 1.56 → 1.51 (faster)

→ Shoulder IR imbalance: 18% → 3% (healthier)

Heavier, faster, more powerful, and more balanced — at the same time. That’s not the story the “don’t lift heavy” crowd tells, but it’s what the data shows. Pitching happens in ~150ms, and DJ’s ability to produce force fast nearly doubled. That’s where velocity comes from.

Now — heavy isn’t a free-for-all. It has to be built the right way, on good movement, and it’s not the only lever. Some pitchers need strength, some need speed, some need arm health. Most need to stop guessing.

That’s why it starts with the Initial Performance Evaluation: a full VALD ForceDecks + DynaMo read on exactly what’s limiting you, built into your plan.

Most gyms sell workouts. We run a system.

A workout is one session. A system is what makes the next 12 weeks actually add up — on the field and in front of college coaches.

The PSP Method, 5 stages:

→ ASSESS — objective baselines. Force plates, sprint times, strength, arm-health. Real numbers, not a vibe check.

→ PLAN — your data builds the program. Not a template off the shelf.

→ TRAIN — coached, tracked, progressive. Work with intent.

→ MEASURE — we re-test. Progress gets proven, not assumed.

→ SHOWCASE — coach-ready proof that gets you seen.

Then we run it again. Every cycle, you out-train the last one.

That’s how a raw athlete becomes a measurable, recruitable one.

If you don’t know where you’re at, you’re guessing at what to improve.

Why we put every athlete through an IMTP as part of PSP’s Initial Performance Evaluation on Day 1.

The Isometric Mid-Thigh Pull is a 5-second pull against an immovable bar on the ForceDecks.

One movement, four metrics:
→ Peak Force. How much engine the athlete has in the legs and hips. The strength foundation everything else is built on.
→ Relative Peak Force. Lets us compare a 14-year-old to a college infielder fairly, and gives us a baseline to hold or grow as the athlete adds lean mass over the next 2-3 years. Why some 180LB guys pop 105MPH EV.
→ Rate of Force Development. How much force the athlete can produce in the time window sport actually allows — the difference between strong in the weight room and explosive on the field.
→ Left-right asymmetry. Imbalances quietly cost performance and raise injury risk.

And IMTP is just one of seven tests in the PSP Initial Performance Eval — to give us a complete picture of the athlete.

Every athlete leaves with a branded report. GAR-coded. Benchmarked against thousands of HS, college, and pro athletes in the database. Tied directly to immediate training priorities, and allowing us to set highly specific targets between now and your next test.

You can’t out-train what you haven’t measured.

Most “plyos” you see on Instagram are just sloppy jump training.

No collision.
No rebound.
No real stimulus.

If you want a specific adaptation, you have to train the demand that creates it.

Random work builds random results.

Reactive strength and elasticity require high-velocity, short-contact exposure — not just jumping.

Watch & on the loaded hurdle hops:
ground contacts in the 250–300ms range, repeatable, scalable, and built around the exact quality we’re chasing.

Same thing with upper-body power.

A thousand med ball throws won’t matter if the athlete can’t absorb force, stabilize it, and redirect it explosively.

Watch on the bear squat overhead throw:
the collision and explosive redirect — that’s why the drill works.

The eccentric demand matters.

Every rep in our gym has a target.

Every training block has a purpose.

Every athlete has a plan built off what their assessment says they actually need.

That’s how training transfers:
to velocity, exit velo, speed, durability, and performance that actually shows up in competition.

Train the adaptation. Not the activity.

Your arm isn’t tired. It’s weak.

There’s more velo and more frequent max-intent throwing in today’s game — and with it, a rise in forearm and elbow injuries.

The flexor-pronator mass — the muscles on the inside of the forearm — acts as a dynamic stabilizer for the UCL. When it isn’t strong enough to handle the volume and intensity of throwing, it’s susceptible to strain. That’s the pipeline to chronic issues and acute injury.

Here’s a thought: rather than babying the arm all season (the thing taking the brunt of the stress every time you throw), train it. Being intentional with exercise selection, volume, and intensity to maintain — and even sustainably build — capacity in the tissue doing the work isn’t just doable. It’s logical.

At PSP, in-season arm care isn’t random rehab work. It’s targeted maintenance to preserve strength, tissue capacity, and durability through the season.

The goal in-season isn’t to build from scratch.

It’s to maintain what was built all winter — and keep you on the mound.

Strong arms throw hard.

Strong arms stay healthy.

In-season pitchers don’t need more.

They need the right things, dosed correctly.

DB Lateral Raise. DB Preacher Curl. Overhead Cable Tricep Extension.

Single-joint work like this, paired with the right volume and intensity, is one piece of how we keep arms strong and joints durable through a season.

Most programs avoid these exercises for pitchers — especially in-season — for the exact reason they are valuable.

The throwing arm takes the brunt of the damage.
So don’t baby it. Train it. Intentionally, with enough stimulus to keep it strong, capable, and ready to absorb what the season demands.

High enough to drive adaptation. Low enough to keep the arm fresh for the next outing.

This is the part of the model that quietly keeps pitchers healthy through May, June, and into summer ball. Strong cuff. Durable elbow. Resilient connective tissue. A throwing arm that handles the season instead of surviving it.

If your son is pitching this spring and you don’t know where his shoulder, elbow, and trunk capacity actually stand — that’s the gap.

Velocity, spin rate, exit velo — these tell you what an athlete can do.

They don’t tell you what the arm can handle.

That’s a different question, and it requires different numbers. Two of them. And almost no one is measuring them in-season.

ER:IR Ratio — a window into shoulder balance.

The external rotators handle the eccentric load on the back end of every throw. When they’re balanced against the internal rotators, the shoulder controls deceleration well. When that balance drifts — usually toward IR dominance as fatigue accumulates — more stress can shift down the chain toward the elbow.

It’s a snapshot of how the shoulder is tolerating the work.

Grip Strength — a very underrated monitoring tool in baseball.

Grip is a practical proxy for the flexor-pronator mass — the muscles on the medial side of the elbow that support the UCL during high-velocity throwing.
But here’s the part most people miss: grip is also a fatigue marker. When it drops between outings, the system is accumulating stress faster than it’s recovering.

The real value is the combination.
ER strength tells us about proximal capacity. Grip tells us about distal readiness. Together, they show us how the arm is tolerating the season — week to week, outing to outing.

One number is a snapshot. A trend is a story.

A single reading doesn’t tell us much. The same number compared to that athlete’s baseline — and tracked across the season — tells us when stress is outpacing recovery.

Numbers that shift under workload and recover between outings? A healthy arm. Numbers that stay suppressed week after week? An arm that needs intervention.

We test at intake. We retest in-season. We use the data to drive programming decisions — pull back volume when the numbers say so, push when they say it’s safe.

If you’ve never tested these — or you tested once and never again — you’re working blind during the most important months of the year.

DM us to schedule an assessment and find out what your arm is actually telling you.
