The KHAOS® Waterboy Junior™ is a portable, water instability training tool designed to enhance arm efficiency, glove skills, and body awareness. Ideal for runners, catchers, pitchers, and rotational athletes, it strengthens muscles and improves coordination for peak performance.
Key Benefits:
- Arm Efficiency – Develop a powerful, controlled arm swing for running and throwing.
- Glove Skills – Improve quickness, ball transfers, and glove awareness for catchers.
- Glove Side Control – Enhance extension and alignment for pitchers.
- Body Awareness – Boost proprioception and movement control for better athletic performance.
- Functional Strength Training – Strengthen upper arm and shoulder muscles for endurance and injury prevention.
- Versatile Use – Ideal for baseball, tennis, volleyball, and other sports.
How It Works
The KHAOS® Waterboy Junior™ features a small, tubular container filled with water, worn on the forearm. The unstable water movement challenges muscles and the nervous system, improving coordination, endurance, and arm health.
Why It’s Effective
- Dynamic Systems Theory (DST) – Encourages adaptation and skill development.
- Constraint-Led Approach (CLA) – Water instability modifies movement patterns for efficiency.
- Chaos Theory – Unpredictable water shifts enhance neuromuscular control.
- Proprioceptive Training – Constant feedback improves body awareness and motor control.
Key Features
✅ Water Instability Training – Creates dynamic resistance for strength and coordination.
✅ Comfortable Design – Snug fit for optimal training comfort.
✅ Versatile Use – Benefits athletes across multiple sports.
✅ Durable Construction – Built for long-lasting performance.

Frequently Asked Questions
Yes! The low-impact water resistance makes it ideal for rehabilitation and recovery training.
Gentle resistance strengthens injured muscles without causing excess strain. Controlled instability improves joint stability and movement accuracy. Gradual progression allows athletes to rebuild arm strength and coordination safely.
For athletes returning from injury, the KHAOS® Waterboy Junior™ provides an effective rehabilitation tool that enhances range of motion, proprioception, and endurance without excessive load on joints.
The KHAOS® Waterboy Junior™ is built for intense training with high-quality materials and reinforced construction, making it an excellent investment for athletes seeking high-quality instability training.
- Premium durability ensures long-term performance, even during rigorous workouts.
- Comfortable, yet secure fit allows for extended training sessions without discomfort due to its soft neoprene straps.
- Reliable design withstands repetitive motion drills, dynamic training sessions, and sport-specific training applications.
Deciding on purchasing a single unit vs. a pair often comes down to the specific athlete and their specific goals for the Khaos® Waterboy Jr™.
Key Factors to Consider:
- Single Unit – Ideal for athletes focusing on unilateral training, arm efficiency, or one-sided movements like pitching, throwing, or catching drills.
- Two Units – Recommended for bilateral training, improving symmetry, full-arm coordination, and balanced strength development for both arms simultaneously.
How to Decide:
For pitchers, runners, or sport-specific arm training: One unit is often enough to refine glove skills, throwing mechanics, and coordination. For full-body movement drills, balanced training, or strength symmetry: Two units ensure both arms experience equal dynamic resistance, enhancing body awareness and functional strength.
The KHAOS® Waterboy Junior™ is designed with a universal fit, making it adaptable for athletes of various sizes and skill levels. Its adjustable straps ensure a snug yet flexible fit, allowing users to adjust placement for comfort and optimal training effectiveness.
- The lightweight, compact design accommodates different arm sizes while maintaining proper stability and resistance.
- The adjustable straps, combined with the soft neoprene isolator, make for a water-based training tool that anyone can use comfortably.
Proper care ensures durability and performance.
Routine cleaning:
- Wipe exterior with mild soap & water after each use.
- Dry completely before storing.
Regular maintenance:
- Empty and rinse interior to prevent mold or mildew.
- Inspect filler port, handles, and stitching for wear & tear before each use.
- Store in a cool, dry place, away from sharp objects.
The KHAOS® Waterboy Junior™ stands out from other water instability training tools due to its secure dual-strap design, leak-proof locking valve, and opaque construction.
Dual-Strap Forearm Attachment for Maximum Stability
- Unlike competitors that rely on single-strap or loose-fitting designs, the KHAOS® Waterboy Junior™ features two adjustable straps that securely attach to your forearm.
Locking Valve System to Prevent Water Leaks
- Many instability training tools suffer from leakage issues, reducing effectiveness and longevity. The KHAOS® Waterboy Junior™ is equipped with a locking valve system, ensuring the water will remain inside.
Opaque Design to Limit Mold and Mildew Visibility
- Competitor products often use clear plastic, which can show mold or mildew growth over time. The KHAOS® Waterboy Junior™ is designed with opaque materials, preventing visibility if mildewing does occur.
