The counter-movement jump (CMJ) is a movement that is utilized in nearly every sport. An athlete may perform a CMJ when going up for a rebound in basketball, receiving a pass in football, making a block in volleyball, and so on. When you break a CMJ down to its fundamental characteristics you find more than the simple act of jumping. At its core, the CMJ is the explosive extension of the hips, knees, and ankles. This movement can be mimicked and loaded through traditional weightlifting movements like the snatch and clean. Loaded movements present an easy model of improvement with load increases scaling up with training.If you want to know how many apples are in an orchard, you count the apples – not the apple trees. When we use jumps as a metric for power, we’re comparing apples to apples.
