Weightlifting

Weightlifting requires a combination of power (strength and speed), technique, flexibility and consistency. A weightlifter's strength comes primarily from the legs, specifically the muscles of the quadriceps and posterior chain, and secondarily the back, anterior core, and shoulders as well as all round ratio development. Weightlifting is a full body activity including even the minor muscles, but these muscles receive emphasis over the others within the body. Weightlifters need not necessarily be heavy, as they compete by weight classes.This is Also the powering of muscles

The competitive sport is controlled by the International Weightlifting Federation (IWF). Based in Budapest, it was founded in 1905.

Competitors compete in one of eight (seven for women) divisions determined by their body mass. These classes are currently: men's: 56 kg (123 lb), 62 kg (137 lb), 69 kg (152 lb), 77 kg (170 lb), 85 kg (187 lb), 94 kg (207 lb), 105 kg (231 lb), and over 105 kg; and women's: 48 kg (106 lb), 53 kg (117 lb), 58 kg (128 lb), 63 kg (139 lb), 69 kg (152 lb), 75 kg (165 lb), and over 75 kg. In each weight division, competitors compete in both the snatch and clean and jerk, and prizes are usually given for the heaviest weights lifted in the snatch, clean and jerk, and the two combined.

The order of the competition is up to the lifters—the competitor who chooses to attempt the lowest weight goes first. If they are unsuccessful at that weight, they have the option of reattempting that lift or trying a heavier weight later (after any other competitors have made attempts at that weight or any intermediate weights). Weights are set in 1 kilogram increments (previously 2.5 kg increments), and each lifter can have a maximum of three lifts, regardless of whether lifts are successful or not.

The title "best lifter" is commonly awarded at local competitions. The award is based on the lifters' Sinclair Coefficients, which calculate strength-to-weight ratio of the lifters. Typically, the winner of the heaviest weight class will have lifted the most weight, but a lifter in a lighter weight class will have lifted more in proportion to his bodyweight.
