HOW IT WORKS
Three Steps.
Real Results.
1.
film your throw
Use your phone. No special equipment needed. Just you, a ball, and somewhere to throw.
2.
UPLOAD TO SPINLAB
Our system measures your arm speed, peak hip rotation, peak torso rotation, velocity efficiency, and full joint angles across every phase of your throw within minutes.

WHAT SPINLAB MEASURES
your velocity.
by the numbers.
These are the exact metrics in your SpinLab report — the ones that determine how hard and how far you throw.
ARM SPEED
Peak speed of your throwing arm during your motion. The most direct measure of how hard you throw — and where velocity gains show up first.
30.2
MPH
RELEASe TIME
Milliseconds from start of throw to ball release. Every unnecessary millisecond is time a defender has to close on you or a window has to close.
437
ms
HIP ROTATION SPEED
Peak rotational speed of your hips in degrees per second. Your hips generate the power your arm delivers — this is your engine.
1179
DEG/S
TORSO ROTATION SPEED
How fast your torso transfers power from your hips to your arm. A lag here is one of the most common velocity killers SpinLab finds.
942
DEG/S
Sequencing score
Are your hips, torso, and arm firing in the correct order? Elite QBs score 90%+. Out-of-sequence firing kills velocity before it starts.
100
/100
acceleration score
How effectively you build speed through the throwing motion from foot strike to release. Low scores mean you're not loading your throw properly.
95
/100
Deceleration score
How well your arm decelerates after release. A poor score means your follow-through is inconsistent — which signals broken mechanics earlier in the throw and puts stress on your arm.
83
/100
Velocity Efficiency Score
How much of the power your body generates actually makes it to the ball. A low score means velocity is leaking somewhere in your chain.
76
/100

This Is What
SpinLab Found.
These are the exact metrics in your SpinLab report — the ones that determine how hard and how far you throw.
BEFORE
26.4 MPH
Arm Speed
After 60 Days
31.4 MPH
Arm Speed
Velocity Efficiency Score of 61/100
Major power leaking between hips and arm
→ Hip-to-torso timing drills improved score to 79 in 6 weeks
Hip and torso rotation peaking at the same time
Zero lag means zero power transfer
→ Sequencing drills separated the peaks, score went from 74% to 93%
Acceleration Score of 68/100
Not building enough speed through the motion
→ Stride length and hip load work brought score to 81
“I had no idea why I was plateauing. We tried several different coaches. SpinLab showed me what was lacking with one upload. Added 5 MPH to my arm speed and 14 yards in 60 days.”

frequently asked questions
Real answers.
Do I need special equipment?
No. Just your phone. Film your throw from the side, upload the video, and SpinLab does the rest. No sensors, no special cameras, no setup.
How is this different from my coach watching me throw?
Your coach sees what the eye can see. SpinLab measures what the eye can’t see. Most coaches who use SpinLab say it catches things they've been missing for years.
How fast do I get my results?
Fast. Most reports are ready within 10 minutes of upload. You're not waiting days for feedback — you get it while the session is still fresh.
What if I don't see improvement?
SpinLab shows you exactly what to fix. If you do the work, the data will show the improvement — often within 60 days. QBs who upload consistently and follow their drill recommendations see measurable gains in distance and accuracy.
Can I cancel anytime?
Yes. Anytime. No contracts. No cancellation fees. Cancel in under 30 seconds from your account settings.
