Overview
The ProsourceFit medicine ball, this listing the 8-lb version, is a textured rubber ball built for tossing, catching and core work, sized at 9 inches in diameter across ProsourceFit's 4 to 12-lb range.
What stands out in owner feedback is the 9-inch diameter holding steady across weights, where some competing medicine balls jump to a 12-inch ball at a similar weight, which matters for anyone wanting a size they can control overhead or in fast partner tosses. It's also used off-label for myofascial release, though ProsourceFit doesn't market it that way.
- Textured rubber surface for a secure grip
- 9-inch diameter across the 4 to 12 lb range
- Moderate bounce for wall-toss and partner drills

Performance notes

Frequently asked questions
What diameter is the ProsourceFit medicine ball?
It measures roughly 9 inches across its weight range, which owners note is smaller than some competing balls at the same weight.
Can it be used as a slam ball?
It can occasionally, but owners recommend not using it as a slam ball regularly since that wears the rubber faster than catch-and-throw use.
Is it good for myofascial release?
Some buyers use the lighter versions of this ball for myofascial release work, though that's an owner use case rather than the primary marketed purpose.
