Weight training or load training is a common form of exercise, in which the force of gravity is used (through discs, dumbbells, pulley machines and / or levers) that opposes muscle contraction.

Done properly, weight training can provide significant functional benefits, such as: increased muscle tone, increased muscle mass, aid in weight loss, and improved overall health and well-being.

Weight training is used in various sports, as a complement to the training plan, and in rehabilitation; but the sports from which this type of exercise is directly derived for strength training are bodybuilding, weightlifting, powerlifting, Olympic wrestling, strongman and CrossFit.

Each part of our body has its own limits regarding range of motion and function.

Each one behaves and supports loads or weights according to the characteristics of each individual and the way in which he performs his training with weights.
