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.

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.

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.

Out-Train. Out-Perform.

155lbs. Seated Good Morning. Full ROM.

Most athletes would fold in half attempting this. didn’t start here either.

He followed a structured progression consistently over a long period of time:
→ Pick a weight you can hit for 6 reps
→ Stay there until you hit 12 with it
→ Drop back to 6, add load
→ Repeat

What you’re watching isn’t a max effort. It’s the byproduct of a kid who showed up and progressed the movement the right way for a long time.
The result?

Tissue that doesn’t break. A spine that absorbs and transfers force instead of leaking it. A torso that connects what the hips produce to what the upper body delivers — every sprint, every cut, every collision.

Distal strength expresses what the proximal chain allows. Build the middle of the body, and the extremities have something worth transmitting.

Out-Train. Out-Perform.
