The vertical jump is a beginner-level plyometric, i.e., a lower-body explosive exercise.
Most everyone has done one of these.
Begin by assuming the universal athletic position, i.e., semi-squat as in photo below.
Next, thrust with both legs as hard as you can and also thrust your arms upward so that they help you gain vertical momentum. You should try to jump as high as you can.
Land back in the starting position to begin next repetition. Repeat for desired reps and sets; rest no longer than 45 seconds between sets, no rest between reps.
