AssetID: 84120695 / {name:’extraPriceParams’,value:{}0 / Cut out of a kettle bell on white background Weight training is a common type of strength training for developing the strength and size of skeletal muscles . It uses the weight force of gravity (in the form of weighted bars, dumbbells or weight stacks) to oppose the force generated by muscle through concentric or eccentric contraction . Weight training uses a variety of specialized equipment to target specific muscle groups and types of movement. Weight training differs from bodybuilding , Olympic weightlifting , powerlifting , and strongman , which are sports rather than forms of exercise. Weight training, however, is often part of the athlete's training regimen. Description above from the Wikipedia article Weight training, licensed under CC-BY-SA full list of contributors here.
