What is the term for an individual weight used in strength training that can vary in size?

Dumbbells are the term used for individual weights in strength training that come in various sizes and weights. They typically consist of a short bar with a weight at each end, allowing for a wide range of exercises targeting different muscle groups. The versatility of dumbbells enables users to perform unilateral exercises (working one side of the body at a time) or bilateral exercises (working both sides simultaneously), making them a staple in resistance training programs.

Dumbbells are particularly effective for increasing muscle strength and endurance because users can easily adjust the weight to match their fitness levels and goals. This adaptability allows individuals to gradually progress in their training as they become stronger, which is an essential principle of strength training. Additionally, the variety of sizes available ensures that dumbbells can accommodate users from beginners to advanced athletes, enhancing their suitability for diverse training regimens.
