Overview
D-Ball Medicine Balls are versatile, high-durability training tools that bridge the gap between a traditional medicine ball and a slam ball. Proudly made in the USA, these balls feature a unique gel-filled interior and a rugged, textured rubber shell. They are designed to produce a consistent "dead bounce," making them safe and effective for high-intensity overhead slams, while their grippy surface ensures control during traditional medball exercises like wall tosses and core rotations.

Key Features and Specifications
Made in the USA: Manufactured to high standards for long-term durability.
Three Functional Classes:
Keystone Speed Ball: 8LB and 10LB increments (9” diameter).
Keystone Strength Ball: 12LB, 16LB, 20LB, and 25LB increments (9” diameter).
Super Ball: 30LB, 35LB, and 40LB increments (10.6” diameter).
Construction: Heavy-duty rubberized shell with a soft-textured grip and grooves.
Internal Filling: Specialized gel-like filling that creates a dead-bounce effect and prevents shifting during use.
Consistency: Most weights share a uniform 9" diameter, ensuring consistent leverage and hand placement as you progress in strength.
Color: Classic Black with molded Rogue branding.
Performance Benefits
Hybrid Versatility: Unlike vinyl medballs, D-Balls are fully optimized for overhead slams. They provide the training benefits of catching and throwing without the high rebound of standard rubber medballs.
Explosive Power Development: Perfect for high-velocity slams, cleans, and throws that mimic Olympic lifting benefits by challenging range of motion and core stability.
Superior Grip: The combination of a soft rubber texture and molded grooves ensures a secure hold even during high-rep sets when hands are sweaty.
Dead-Bounce Design: Hits the floor and stays there (with minimal rebound), requiring the athlete to perform a full reset and lift for each repetition, maximizing metabolic output.
Maintenance and Care
Surface Recommendation: For maximum shell life, only use D-Balls on smooth, non-abrasive surfaces like rubber gym mats or wooden floors. Avoid slamming on concrete, asphalt, or gravel, as this will grind down the rubber shell and void the warranty.
Cleaning: Wipe the textured shell with a damp cloth and mild soap. Avoid petroleum-based cleaners that can damage the rubber.
Pressure Management: Most D-Balls are designed to maintain their shape without additional inflation. Do not attempt to add air unless the specific model features a visible and accessible inflation valve.
Storage: Store on a flat surface or a specialized medball rack. Avoid extreme heat or prolonged direct sunlight, which can affect the flexibility of the rubber shell.
Warranty Information
Warranty Period: Includes a Two-Year Warranty for individual use and a One-Year Warranty for commercial use.
Exclusions: Warranty is voided if the ball is used on abrasive surfaces (concrete/asphalt) or if it shows signs of user alteration or negligence.
Frequently Asked Questions
Q: How do these compare to the Rogue MK D-Balls? A: Standard D-Balls are smaller and more compact (9" to 10.6" diameter), making them easier to maneuver for high-speed conditioning. The MK D-Balls feature a consistent 14" diameter across all weights to mimic a standard wall ball size.
Q: Are these better for slams than the Echo Slam Balls? A: Both are excellent for slams. D-Balls have a unique "gel-filled" feel and a slightly softer shell texture, which some athletes prefer for catching and pressing. The Echo Slam Ball is a more traditional hard-shell slam ball with zero rebound.
Q: Will the ball lose its shape over time? A: No. The internal filling and thick rubber shell are engineered to stay spherical even through thousands of heavy slams and tosses.
Q: Can I use these for wall ball shots? A: Yes. While they are denser than vinyl medballs, they are highly effective for wall balls. Note that because they have a dead bounce, they will not bounce off the wall as much as a standard medball.
