Overview
A soft, vinyl-shelled wall ball from JFit built for wall squats, throws and core work, not for slamming. This listing's model points to the 15 lb gray version, out of a family that spans 4 to 30 lbs.
JFit is explicit that this ball isn't meant for slam-style training, so it's suited to controlled wall throws, squats and rolling out sore muscles rather than repeated drops onto concrete. Every weight uses the same 14-inch diameter except the 4 lb ball, which is 9 inches.
- Available 4 to 30 lbs
- 14-inch diameter (9-inch on the 4 lb ball)
- Laser-cut, double-stitched, hand-stuffed shell
- Non-slip grip surface
Who it's for
Suits strength and conditioning work like wall squats, presses and functional drills where a soft, grippy ball matters more than bounce. Not the right pick if slam-ball training is the point, since the maker specifically doesn't recommend it for that.
Strengths and trade-offs
Drawn from this product's published specifications.
- Non-slip vinyl grip for sweaty hands
- Hand-stuffed for balanced, even weight
- Doubles as a muscle roll-out tool
- Consistent 14-inch diameter across most weights
- Not built or rated for slam-ball training
- 4 lb ball is smaller, only 9 inches
Performance notes
The laser-cut, double-stitched vinyl shell is hand-stuffed to keep an even weight distribution and hold its shape through repeated wall throws, and the non-slip surface is meant to stay grippy through sweaty sessions.
