The composition of implements used for resistance training varies significantly depending on intended use, cost, and desired durability. Common materials include cast iron, steel, and concrete, each offering a distinct balance of density, cost, and manufacturing complexity. Protective coatings such as rubber, vinyl, or neoprene are frequently applied to enhance grip, reduce noise, and protect flooring.
The choice of material impacts both the performance and longevity of these implements. High-density materials like steel allow for compact designs, facilitating easier handling and storage. Economical options such as concrete, while functional, may be less durable and require larger volumes to achieve a specific mass. The application of coatings provides a layer of protection against corrosion and physical damage, extending the usable lifespan.
