Weightlifting is generally defined as a sport or activity in which barbells or other weights are lifted. In modern and competitive weightlifting, there are two standard lifts: the snatch (during which the chosen weight is lifted in a single movement from the floor to an extended position), and the clean and jerk (during which the weight is moved from the floor knee level in a deadlift, dipped as the athlete squats and aligns the elbows to a front rack position, moving the bar to shoulder level, then pressed into an extended position overhead in multiple distinct movements).
The clean and jerk has no time restriction and is known to challenge several muscle groups in just a few movements, including the core, quads, back, glutes, and shoulders. It’s a highly popular technique in both Olympic weightlifting, and in CrossFit programmes.
