VELO by The Bullpen Training VELOBall Weighted Plyometric Baseball Set — 4 Regulation-Size Balls (5oz, 8oz, 11oz, 14oz) for Bat Speed

These plyometric baseballs from VELO by The Bullpen Training look and feel like real baseballs but vary in weight to force each swing to recruit more muscle and deliver immediate feedback. The set contains four unmarked, identical-looking balls so hitters cannot predict weight, a drawstring carry bag, and access to curated practice videos from founder and athlete Jax Vassallo. Use them in batting practice, tee work, or soft toss to train explosiveness and reinforce efficient mechanics without changing ball size or grip.

How does using weighted plyo baseballs improve bat speed and power?

Training with progressively heavier baseballs increases the load muscles must overcome during the swing, which encourages greater force production and faster acceleration when returning to standard-weight balls. Because the balls match regulation size, the movement pattern stays sport-specific, so gains transfer directly to live hitting.

• Progressive overload from 5oz → 14oz strengthens forearms, wrists, and core.
• Unpredictable weight forces hitters to apply full effort on every swing.
• Same diameter maintains proper grip, path, and hand placement.

What kind of instant feedback will I get during batting practice?

The VELOBall set gives clear tactile and flight feedback: solid contact produces smooth, longer trajectories, while poor contact distorts the ball’s path or flight. That immediate response helps hitters adjust mechanics in real time, making practice more efficient and corrective.

• Heavier balls reveal weaknesses in weight transfer and timing.
• Flight and ball deformation indicate point-of-contact quality.
• Consistent feedback accelerates motor learning and correction.

How should I incorporate the four-weight set into my training plan?

Start with the lightest ball for short, focused reps to groove path and timing, then gradually introduce heavier balls to build strength and speed. Alternate weights within a session or across days to challenge neuromuscular control and prevent adaptation plateaus.

• Warm up with the 5oz ball for 8–12 controlled swings.
• Mix 8oz and 11oz for power-focused rounds and bat speed work.
• Use the 14oz sparingly for overload reps and strength testing.

What’s included and how do I carry or store the set?

The kit contains four regulation-size weighted VELOBalls (5oz, 8oz, 11oz, 14oz), a drawstring carrying bag for easy transport, and a VELO by The Bullpen Training sticker that outlines recommended drills. The identical color scheme keeps weight unpredictable during drills, and the compact bag fits neatly in most gear totes.

• Four unmarked weighted baseballs for progressive training.
• Drawstring carry bag for practice, travel, and storage.
• Access to training videos from Jax Vassallo included.

Who is this for? The VELOBall Hitting Plyometric Baseball Set suits hitters at high school, college, and adult amateur levels who want baseball-specific strength and swing improvements. Coaches, trainers, and serious players seeking measurable, transferable gains in bat speed and mechanics will benefit most. It’s ideal for athletes who already have solid fundamentals and want to add a targeted overload tool to their batting practice toolbox.
