The deadlift is a weight training exercise where one lifts a loaded barbell off the ground from a stabilized bent-over position. It is one of the three gauges of powerlifting, and is an exercise for overall body development. The deadlift is a compound movement that works grip strength with the erector spinae, gluteus maximus, adductor magnus, hamstrings, and quadriceps serving as the primary muscles. The remaining muscles are involved in stability control. It is, in a sense, the purest test of strength because it is one of the few lifts of dead weight (weight lying on the ground).
In most other lifts there is an eccentric phase (lowering) followed by the concentric phase (lifting). The eccentric phase essentially stores some amount of energy in the stretched muscles and tendons, making the concentric phase somewhat easier. the deadlift, however, is solely a concentric movement. The lift begins at its most difficult point, with no inertia or stored energy. The record for a raw deadlift (a deadlift performed without the aid of a deadlift suit where only a belt is allowed) is 1015 lbs by Benedikt Magnússon of Iceland.
