Weights are exercise equipment used for strength training and are typically made out of iron or other metals. They are used to generate resistance against lift. Whenever weights are lifted against gravity they offer resistance due to their gravitational pull. Repeating this activity on a sustained basis increases muscle strength, size and tone.
Weights come in different shapes and sizes, the most common of which are dumbbells. These are used for developing strength in the biceps, triceps and forearms. Weights such as dumbbells are made of iron and have round spheres or flat discs at each end of a bar. Weight training is done by lifting this bar up and down along the natural plane of the arm. Weights are fixed on either end of a bar and the space in between serves as a grip for users to hold.
Barbells are longer bars which are 2.2 metres in length. The ends of the barbell have threads which help in fastening the steel plates with the help of a large screw or wing nut. The plates used to secure the weights on a bar are called collars and are usually five pounds in weight. A bar should have two collars, one at each end. Barbells have a ridge at the end of the grip area which works as a stopper and prevents the weight plates from sliding onto the grip area.
Weight lifting features in the Olympics using different metal plates that are colour coded according to their weight. Weights have a rubber coating around their edges to avoid damaging the floor when they are often dropped by weight lifters and athletes. Weights are also worn as ankle or wrist bands during jogging or running to increase resistance. Weights need to be used with care, especially around children. Weight training should be done under supervision as unsupervised usage can be risky and may lead to injuries.
