Program results shared with the head coach's permission. Individual results vary โ but the system works when you use it.
What Actually Changes
The Outcome You're Actually Buying
Not a bat. A measurable jump in the numbers scouts, college coaches, and box scores care about โ with no swing thoughts required.
+ Bat Speed
Explosive acceleration through the zone. Faster hands, faster barrel, faster decisions.
+ Exit Velocity
Harder contact through cleaner sequencing. Warning-track fly-outs turn into extra bases.
+ Batting Average
Better swing path = more barrels. More barrels = more hits. Simple math.
+ Doubles & Home Runs
The IUP program hit +57% more home runs in one season. Real numbers, real ballparks.
How It Works
No Thinking. Just Swing.
Overload / underload has been used in elite sport for decades. Complete Game refined it for baseball & softball hitters and packaged it into 4 pro maple bats + a mobile app. The bats do the coaching for you.
Open The App
Off-season, in-season, or pre-game โ hit "play" on the program that matches where you are today.
Take Normal Cuts
Follow the sequence with each of the 4 bats. Short. Long. Heavy. Light. No swing thoughts required.
Your Swing Self-Corrects
Your body reads the load, adjusts, and re-programs connectivity, sequencing, and acceleration โ automatically.
Everything You Get

Inside The Set
Meet The 4 Bats
Every bat has a job. Together, they force your swing to solve a different problem โ and that's exactly the point.
Locks in connectivity. Forces the barrel to stay in the zone longer without collapsing.
Effortless sequencing and body control. Teaches you to move in order โ every time.
Builds real swing strength and power without weight-room noise.
Speed, timing, and whip. This is the bat that shows up in exit velocity readings.
What The Bats Fix
Three Silent Killers Of A Big Swing
Connectivity
The link between your lower half and your barrel. When it breaks, the swing leaks power. The bats put the connection back together โ without you having to think about it.
Sequencing
The order your body has to fire in to actually produce speed. When it's out of order, the barrel shows up late โ every time. The 4-bat set trains the right sequence in without a single swing thought.
Acceleration
Peak barrel speed at contact โ not before, not after. The overload/underload effect trains your nervous system to time the acceleration to the ball.
