Built for solid performance and everyday training, the 1RM Rubber Medicine Balls deliver predictable handling for core work, throws, partner drills and conditioning circuits. The textured rubber surface provides a secure grip - even when hands are sweaty - while the balanced construction keeps the ball rolling and rebounding consistently.
With a thread-wound inner core and heavy-duty rubber outer, these balls are engineered for controlled rebound, even weight distribution and long-term commercial use. They’re ideal for rotational throws, wall work and conditioning where a reliable bounce matters, but they’re not designed for repeated high-force slams like a dead ball.
A recessed, flush-mounted valve eliminates raised edges that can catch on hands, walls or racks - a small detail that makes a big difference in busy gyms. Durable, stable and easy to control, these medicine balls suit home gyms, PT studios and commercial training floors alike, performing session after session without compromise.
This listing is for one (1) 9kg Rubber Medicine Ball.
What makes 1RM Medicine Balls different
Unlike vinyl-shell balls, cheaper thin-wall medicine balls or soft wall balls, 1RM Rubber Medicine Balls use a wrapped, thread-wound internal core. This keeps the weight evenly distributed and allows the ball to rebound consistently instead of folding, deforming, splitting or going dead over time.
The textured rubber shell provides a secure, dry-hand grip for throws, catches and rotational work, while the commercial-grade construction stands up to repeated impact in busy gyms.
They are designed and built for movement, not just for holding weight.
