Overview

This Cap Barbell set bundles six rubber medicine balls at 2, 4, 6, 8, 10 and 12 pounds with a floor rack, color-coded by weight for quick identification in a home or clinic gym.

  • Six color-coded balls: 2, 4, 6, 8, 10 and 12 lbs
  • Textured rubber surface for grip
  • Floor rack included for storage
  • May ship in more than one box

Who it's for

Fits home gyms, physical therapy offices or training spaces that want a full range of medicine ball weights stored off the floor. Not the pick for anyone who wants a single ball or zero assembly.

What buyers say

From Amazon customer reviews.

Owners consistently liked the price and the rack's space-saving design, with several using it in home gyms or therapy offices. The recurring complaint was rack assembly without clear instructions, and a few buyers found a ball under-inflated on arrival or, in one case, one that failed after being pumped up.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Covers a full 2 to 12 pound range
  • Rack keeps six balls organized and off the floor
  • Textured surface gives a secure grip during throws
What to check first
  • Rack assembly has no clear step-by-step instructions
  • At least one ball often arrives under-inflated
  • Assembled rack takes up more floor space than expected

Performance notes

The rack requires an 11/16 socket and a metric wrench, and owners recommend test-fitting the pieces loosely before tightening bolts, since the hoops need to curve upward slightly to hold the balls securely. Once assembled, several reviewers said it held up well and kept a home gym or office floor clear. More than one buyer received a ball that had lost air in shipping, though a bicycle pump was enough to bring it back to size.
