Champion Sports Medicine Ball — 20 lb RPX20 Rhino Promax, 14" Soft Shell, Non-Slip Grip

Built to withstand frequent use in gyms, studios, and home workout areas, this Rhino Promax medicine ball combines a cushioned, impact-absorbing core with a Rhino Skin® synthetic leather cover that holds shape and weight distribution. At a consistent 14-inch diameter across all weights, the RPX20 helps you keep proper form as you progress, while the textured surface improves control during throws and catches. Note: the warranty does not cover repeated slamming on rough surfaces.

How does this medicine ball perform for wall-ball and functional training?

The RPX20 is tailored for wall-ball routines and functional exercises where consistent size and reliable grip matter. Its uniform diameter lets you maintain technique across increasing weights, and the cushioned shell reduces rebound harshness when catching or absorbing impact.

• 14" diameter ensures consistent hand placement and movement patterning
• Non-slip Rhino Skin® cover for secure throws and catches
• Cushioned construction absorbs force for safer repetitions
• Double-stitched seams increase durability during repeated use

Is this ball suitable for high-rep and sweat-heavy sessions?

Yes — the synthetic leather surface is designed to keep grip when hands get sweaty, and the soft shell is comfortable to catch throughout long sets. However, it's not intended for repeated slamming onto concrete or abrasive floors, which can void the warranty.

• Textured, ergonomic surface maintains grip under sweat
• Soft, impact-absorbing shell reduces hand fatigue
• Durable Rhino exterior stands up to daily conditioning work (with proper use)
• Avoid repeated ground slams on rough surfaces to preserve warranty

How do I choose the right weight and how will it help progression?

The RPX20 at 20 lb is a mid-to-heavy option for athletes improving power, core stability, and coordination. Start with a lighter weight to learn movement patterns and increase resistance as strength and technique improve; the constant diameter makes this transition seamless.

• Available in 4–30 lb—pick based on experience and exercise type
• Use lighter balls for speed and technique, heavier for power and load
• Consistent size prevents form changes during weight progression
• Works for wall balls, squats, throws, presses, and plyometrics

What maintenance and storage tips extend the ball’s life?

Keeping the ball away from rough, abrasive floors and cleaning the surface after sweaty sessions preserves the Rhino Skin® shell. Store on a rack or shelf in a dry area and avoid excessive compression or sharp objects to maintain shape and stitching integrity.

• Wipe down the cover with a damp cloth after use
• Do not slam repeatedly on concrete or abrasive surfaces
• Store on a proper medicine ball rack or off the floor
• Inspect seams periodically for wear and replace if stitching frays

Who this is for: The Champion Sports RPX20 Rhino Promax 20 lb medicine ball fits athletes, coaches, and home gym users who need a reliable, mid-heavy training tool for wall-ball drills, functional strength work, and conditioning. It’s geared to those who value consistent size for technique, a secure non-slip grip for fast-paced sessions, and a cushioned shell that makes catching and throwing more forgiving—provided it’s used on suitable surfaces and stored properly.
