How Data-Driven Training Produces Real Results: Inside REBUILT's Approach

"What gets measured gets improved."

It's a simple principle, but most training facilities completely ignore it. Athletes show up, work hard, sweat, and leave. But nobody's actually tracking whether they're getting faster, stronger, or more powerful.

At REBUILT Performance, we do things differently. We track everything. Every sprint. Every jump. Every lift. Every metric that matters for athletic performance.

This isn't about collecting data for the sake of data. It's about using objective measurements to ensure every athlete is actually improving, not just training hard.

The Problem with "Feel-Based" Training

Here's what happens at most gyms and training facilities:

Athletes come in and work out. They feel tired, so they assume they're getting better. Coaches give the same program to everyone because that's easier than individualizing. Nobody knows if the training is actually working because nobody's measuring results.

Then three months later, nothing has changed. The athlete isn't faster. They haven't gotten stronger. Their vertical jump is the same. But they've spent time and money "training" with nothing to show for it.

This is exactly what we refuse to let happen at REBUILT.

What We Actually Measure

When an athlete starts at REBUILT, we establish baseline measurements across every dimension of athletic performance. Here's what we track:

Speed Metrics

• 10-yard sprint - Measures acceleration and starting speed
• Fly 10 - Top-end speed once already moving
• Pro Agility (5-10-5) - Change of direction speed
• L-Drill - Multi-directional speed and agility

We use laser timing gates, not stopwatches. The difference between 4.8 and 4.7 seconds might seem small, but at high speeds, that's the difference between making a play and missing it. We need precise measurements.

Power and Force Production

• Vertical jump - Lower body power output
• Broad jump - Horizontal power production
• Force plate metrics - How much force an athlete can produce and how quickly
• Reactive strength index - How efficiently athletes can use the stretch-shortening cycle

These metrics tell us not just how athletic an athlete is, but specifically where their limiters are. An athlete might have good absolute strength but poor reactive strength. That changes how we program for them.

Strength Measurements

• Back squat - Lower body strength foundation
• Deadlift - Posterior chain and total body strength
• Bench press - Upper body pressing strength
• Power clean - Full body power expression
• Sport-specific accessory lifts - Movements relevant to each athlete's sport

We track one-rep maxes, but also working weights and volume loads over time. Strength isn't just about how much you can lift once—it's about how much quality work you can perform.

Movement Quality

Not everything can be reduced to numbers, but we still assess and monitor:

• Sprint mechanics and technique
• Landing mechanics for injury prevention
• Movement asymmetries that could lead to injury
• Exercise technique and proficiency

An athlete who can squat 300 pounds with terrible form is at high injury risk. We care about how athletes move, not just what numbers they hit.

Why Small Groups Matter

Here's something that might surprise you: we intentionally keep our training groups small.

Could we make more money by cramming 30 athletes into a session? Absolutely. But that would completely undermine everything we're trying to accomplish.

With large groups, athletes become invisible. There's no way to coach technique on every rep. There's no way to monitor every athlete's performance. It becomes a "daycare gym" where athletes just go through motions while coaches count reps.

That's not training. That's babysitting.

At REBUILT, our coach-to-athlete ratio allows us to:

• Coach every set - We see and correct technique in real-time
• Monitor individual progress - We know each athlete's current capabilities and goals
• Adjust on the fly - If an athlete is struggling or crushing it, we can modify their program immediately
• Maintain safety - We can ensure every rep is performed safely
• Build relationships - We actually know our athletes, not just their names

This is the only way to deliver genuinely individualized, high-quality training. You can have large groups or you can have quality coaching. You can't have both.

How We Use Data to Drive Progress

Collecting data is pointless if you don't use it to make better decisions. Here's how we turn measurements into results:

Identifying Individual Limiters

Two athletes might both need to get faster, but for completely different reasons.

Athlete A might have poor acceleration because they lack strength. Their force production numbers are low. For them, we prioritize strength development—squats, deadlifts, building raw force capacity.

Athlete B might have good strength but poor reactive strength. They're slow to produce force. For them, we emphasize plyometrics and Olympic lifts to improve rate of force development.

Same goal (get faster), different approaches (based on their specific data). This is individualization based on objective reality, not guesswork.

Programming with Precision

When we know an athlete's baseline metrics, we can program with surgical precision.

If their vertical jump testing shows they need more force production, we know exactly what loads and volumes to prescribe. If their sprint testing reveals a specific mechanical issue, we know what drills and cues to emphasize.

We're not throwing random exercises at the wall to see what sticks. We're prescribing specific training stimuli designed to address measured deficiencies.

Tracking Progress Over Time

Every 4-8 weeks, we retest key metrics. This lets us see objectively whether the training is working.

If sprint times are dropping and vertical jumps are increasing, we know we're on the right track. If numbers aren't moving, we adjust. Maybe we need more volume. Maybe we need different exercises. Maybe the athlete needs more recovery.

The data tells us what's working and what isn't. We don't have to guess.

Providing Accountability and Motivation

There's something powerful about seeing objective progress. When an athlete sees their sprint time drop from 1.85 to 1.78 seconds, or their vertical increase from 22" to 26", it's undeniable proof that the work is paying off.

This creates a positive feedback loop. Athletes see progress, which motivates them to train harder, which creates more progress. The data isn't just for coaches—it's fuel for athlete motivation.

Not a "Daycare Gym"

Let me be direct about what REBUILT isn't:

We're not a place to drop your kid off so they can hang out with friends while half-heartedly going through workouts. We're not a large group training facility where 40 athletes do the same workout regardless of their needs. We're not a social club that happens to have some weights.

We're a performance training facility where serious athletes come to get measurably better at their sport.

That means:

• Every athlete is held to high standards of effort and focus
• Every session has a specific purpose and goal
• Every athlete gets individual attention and coaching
• Every athlete's progress is tracked and monitored

Yes, our athletes have fun. Yes, they build friendships and enjoy the community. But that happens within the context of serious training, not instead of it.

If you want a gym where your athlete can mess around with their friends, there are plenty of options. If you want a facility where your athlete will actually improve their performance in measurable ways, that's what REBUILT provides.

The Technology We Use

Data-driven training requires the right tools. Here's what we use:

Timing gates - Laser-precise measurement of sprint times, accurate to hundredths of a second. No human error, no stopwatch variance.

Force plates - Measure exactly how much force an athlete produces during jumps and movements. This tells us about power output, force production, and movement asymmetries.

Video analysis - High-speed video lets us break down sprint mechanics and movement patterns frame by frame. Athletes can see exactly what they're doing and what needs to change.

Training management software - Every workout, every lift, every metric is logged and tracked. We can see an athlete's entire training history and progress over time.

This isn't technology for technology's sake. Each tool serves a specific purpose: giving us objective data to make better training decisions.

Real Athletes, Real Results

Let me share some specific examples of how this approach delivers results:

Case Study: Basketball Player

A basketball player came to us as a sophomore with a 20-inch vertical jump. Good, but not elite. Testing revealed that while he had decent strength, his reactive strength index was poor—he wasn't able to express that strength quickly.

We programmed heavy emphasis on Olympic lifts and reactive plyometrics. Within 6 months, his vertical was at 26 inches. By the end of his junior year? 29 inches. That's the difference between getting blocked at the rim and finishing over defenders.

We knew exactly what to target because we measured exactly what was limiting him.

Case Study: Soccer Player

A soccer player was getting beat to balls consistently. Her Fly 10 speed was 13.2 mph—not terrible, but not competitive at the level she wanted to play.

Force plate testing showed she had poor force production in her posterior chain. We programmed heavy deadlifts, RDLs, and hip thrusts. Six months later, her Fly 10 was at 15.1 mph. Her coach asked what she was doing differently because she was beating everyone to the ball.

The answer? Data-driven training that addressed her specific limiter.

Case Study: Football Player

A lineman needed to get stronger but was stuck at a 225lb squat. He'd been "lifting" at his school's weight room for a year with no progress.

The issue wasn't effort—it was programming. He was doing high-rep circuits with no progressive overload. We put him on a structured strength program with systematic progression. Twelve weeks later, he squatted 315 pounds. His coach immediately noticed the difference in how he was moving people on the line.

That's a 90-pound increase in three months. That's what happens when training is actually programmed and monitored.

The REBUILT Difference

Here's what separates REBUILT from other training facilities in the New Lenox area:

We measure everything. Not some things. Not the easy things. Everything that matters for athletic performance.

We keep groups small. Every athlete gets coached, monitored, and pushed to improve. Nobody gets lost in the crowd.

We individualize programming. Your athlete's program is based on their data, their sport, and their goals. Not a cookie-cutter template.

We track progress systematically. Regular retesting shows exactly what's working and what needs adjustment.

We deliver results. Not promises, not hype—actual, measurable improvements in athletic performance.

The Bottom Line

You can't improve what you don't measure. And you can't provide individualized training without objective data about each athlete's capabilities and limitations.

Most training facilities operate on guesswork and generic programming. Athletes work hard but don't see corresponding improvements because nobody's actually tracking whether the training is effective.

At REBUILT, we refuse to accept that approach. Every athlete deserves training that's targeted to their specific needs and proven to deliver results. That requires measurement, small groups, individual attention, and systematic tracking.

It's more work than just running large group classes. It requires better coaching and more sophisticated systems. But it's the only way to consistently deliver the results that athletes and parents expect when they invest in performance training.
