Overview
A sand-filled, PVC slam ball from Amazon Basics with a textured no-slip surface, built as dead weight for CrossFit, HIIT and core training rather than a bouncing medicine ball.
The sand core is what keeps this from bouncing back on a slam, but it also means the ball's weight can shift slightly and feel a little unsettled the first few times you pick it up, something a first-time buyer specifically noticed. Reviewers who slammed it repeatedly report the weight held steady on a scale and the shell showed no early wear.
- Heavy-duty PVC shell with sand-filled core
- Textured non-slip surface
- Dead weight design for controlled slams
- Suited to CrossFit, HIIT and general strength training
Who it's for
Works for home gym or gym-floor slam ball training, core work, and shoulder rehab exercises. Not the choice for anyone who wants a bouncing medicine ball for wall-toss or partner drills.
What buyers say
From Amazon customer reviews.
Buyers found the ball durable with no bounce and a grippy texture that held up through repeated slams, and several used it for shoulder rehab or general strength routines. The one recurring observation was the sand shifting audibly and physically inside the shell, which a first-time slam ball owner found a bit disconcerting even though it did not affect performance.
Strengths and trade-offs
Drawn from this product's published specifications.
- No bounce on slams
- Textured surface grips well when sweaty
- Weight tracks close to the rated figure
- No rubber or tire odor reported
- Sand shift inside the ball feels odd at first
Performance notes
The PVC shell and sand core absorb the impact of a slam so the ball drops and stays rather than rebounding, and the textured surface is what keeps grip through a sweaty set. One reviewer weighed a 20 lb ball at 19.6 lbs on a home scale, close enough to the rated weight to attribute the gap to uneven sand distribution.
