Knowra Dumbbell Dumbbell A short bar with a weight at each end, designed to be held in one hand for resistance exercise. Dumbbells allow each arm to move independently and can be used singly or in pairs.
Biceps curl : An exercise that bends the elbow against resistance to train the muscles at the front of the upper arm. A familiar dumbbell exercise that isolates elbow flexion.
Fixed-weight dumbbell : A dumbbell whose weight cannot be changed by the user. Its permanently attached load makes it simple to select and use.
Barbell : A long bar loaded with weights and typically held with both hands for resistance exercise. Its shared load couples the hands, unlike the independent loading of two dumbbells.
Resistance training : Exercise that makes muscles work against an external force to improve strength, endurance, or muscle size. Dumbbells are one of the equipment types used for this broad training method.
Dumbbell bench press : A chest-press exercise performed lying on a bench with a dumbbell in each hand. It uses paired dumbbells to train the chest while allowing independent arm movement.
Adjustable dumbbell : A dumbbell whose load can be changed by adding, removing, or selecting weight plates. Its changing load lets one implement several training weights with one device.
Kettlebell : A cast weight with a handle above its main body, used for strength and ballistic exercise. Its offset center of mass and handle create different gripping and swinging demands.
Muscular strength : The capacity of a muscle or muscle group to produce force against resistance. Strength is a common adaptation pursued through dumbbell training.
Dumbbell row : A pulling exercise in which a dumbbell is drawn toward the torso, usually from a hinged position. It shows how one dumbbell can load the back through a horizontal pull.
Dumbbell handle : The central grip section of a dumbbell, connecting or supporting its weighted ends. Grip diameter, surface, and shape affect control and comfort.
