Marcy Classic Rubber Hex Dumbbell 12 lb Single

Single 12 lb Dumbbell for Home Strength Training

This single dumbbell weighs 12 lb and is built for home strength training and bodybuilding. Its solid cast iron core is encased in a durable rubber coating that protects floors and reduces noise. A contoured knurled chrome handle provides a secure, slip-resistant grip. The hexagonal ends prevent rolling for stable storage and safe use between sets.

Sustained Load Behaviour During Repeated Sets

The rubber coating maintains its protective qualities and noise reduction over repeated drops and long sessions. The cast iron core does not deform under sustained loading, keeping the weight accurate. Knurled chrome grips resist corrosion from sweat during extended workouts. Flat hexagonal faces stay stable on the floor without shifting during circuit training.

Practical Limits of the Rubber Hex Design

The fixed 12 lb weight cannot be adjusted, so progression requires purchasing additional dumbbells. Available weights include 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, and 55 lb, each sold separately. The single-unit packaging means pairs must be bought as two separate items. Rubber coating thickness limits how many dumbbells fit on a standard rack.
