Overview

The Marcy IBRH-005 is a single 5 pound dumbbell with a cast iron core and rubber coating, finished in black and chrome. The listing quantity is one piece, so this is sold as an individual dumbbell rather than a matched pair.

A rubber-coated cast iron hex head keeps the dumbbell from rolling and protects floors compared to bare iron, while the chrome handle gives grip. Because it ships as one piece, buyers wanting a matched pair for two-handed exercises need to order two.

  • 5 lb single dumbbell
  • Cast iron core with rubber coating
  • Black/chrome finish
  • Hex head shape

Who it's for

Fits buyers filling out a dumbbell rack with specific increments, or anyone who only needs a single light dumbbell for one-arm or rehab-style work. Less suited to buyers expecting a matched pair in one purchase.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Rubber coating protects floors and resists chipping
  • Hex shape prevents rolling
  • Useful for filling a specific weight gap
What to check first
  • Sold as a single dumbbell, not a pair
  • 5 pounds limits use to light or warm-up work

Performance notes

Rubber coating over a cast iron core resists chipping and cushions drops better than bare iron, and the hex shape keeps the dumbbell from rolling off a bench or floor. At 5 pounds, it suits light work, rehab exercises or warm-ups rather than heavier strength training.
