Home gym enthusiasts, these WF Athletic Supply hex dumbbells are built to last! Made from solid ASTM A48 class 20 grey cast-iron with a 1018 cold rolled steel chromed handle, these things are seriously durable - we're talking years of heavy use without bending or breaking. The rubber coating on the hexagon-shaped heads is genius - they won't roll away on you, they protect your floors from damage, and they stay put when you set them down.

The quality is exactly what you'd expect from professional athletic supply equipment - no cheap materials or flimsy construction here.
