Who is UpperDeck Training for?

UpperDeck Training is designed for baseball players who want to develop their physical tools and hitting skills through an assessment-based, technology-driven approach. We work with high school, college, and adult players at all experience levels.

How do I get started?

Book your assessment through our website or reach out directly. Every athlete, regardless of program, begins with a Day One assessment that establishes a baseline and informs everything that follows.

What is the difference between S&C and Hitting Development?

Strength & Conditioning focuses on physical tools, speed, power, and athleticism, measured by VALD SmartSpeed Lasers, jump testing, and medicine ball velocity. Hitting Development focuses on swing mechanics and outputs tracked through Hittrax, combined with approach and mindset development. Many athletes train in both.

Can I do both programs at the same time?

Yes, and many athletes do. S&C and Hitting Development are complementary, physical tools and hitting skills develop together. We will help you find the right schedule and frequency based on your availability and goals.

The Facility

What is UpperDeck Training?

UpperDeck Training is a baseball-specific performance facility located in Sanford, Maine. The facility offers two programs, Strength & Conditioning and Hitting Development, each beginning with a comprehensive assessment on Day One.

All programming is individualized, delivered in small groups of one to five athletes, and tracked using VALD SmartSpeed Lasers, Hittrax batted-ball technology, and medicine ball velocity testing.

Jack LeBlond, CSCS, serves as both Head Strength Coach and Head Hitting Coach, building every program around the athlete's actual baseline, not a one-size-fits-all template.

Our Approach

Measure First.Train Second.Compete Better.

Every athlete who walks through our doors starts with an assessment, not a workout. We measure what matters, build a program around your actual data, and track your progress from Day One. That is how you build real results, not just good sessions.

Technology

Data That Drives Development

We don't guess at progress. We measure it. UpperDeck uses professional-grade technology to assess, track, and prove athlete development over time.

VALD SmartSpeed Lasers: Precise laser timing for 10-yard and 40-yard dash, the gold standard for speed assessment used at the professional and collegiate level.
Hittrax: Batted-ball tracking that captures exit velocity, launch angle, and distance on every swing. Objective hitting data your program is built around.
HackAttack Pitching Machine: Programmable, game-speed reps that prepare hitters for real pitching. High volume. Consistent delivery. Live-arm BP to cap every session.
Medicine Ball Velocity Testing: Rotational power measured through MB throw velocity, the same output that drives bat speed and throwing velocity.

Athletes

What They're Saying

The assessment on Day One was unlike anything I'd experienced. By the end of the first session, Jack already knew exactly what my swing needed. The Hittrax data doesn't lie.

My exit velocity jumped 6 mph over the summer. That's real, measurable progress. Jack tracks everything and the program evolves as you improve.

The S&C program gave us a baseline we could actually train to. Knowing where you start makes all the difference in knowing where you're going.
