The tuck jump is a plyometric exercise that targets the legs, particularly the quads, glutes, and calves. To perform a tuck jump, start by standing with your feet shoulder-width apart. Then, explosively jump up while bringing your knees up towards your chest and tucking them in towards your body. Land back on the ground and immediately jump back up to repeat the movement for the desired number of reps.
In CrossFit, tuck jumps are often used as a conditioning exercise or as part of a high-intensity workout that includes other bodyweight exercises or weightlifting movements. The number of reps and sets can be modified to suit different fitness levels, and the exercise can be combined with other plyometric movements to create more challenging variations. Tuck jumps require proper form and technique to prevent injury, and they are often taught by a qualified coach to ensure safe and effective execution.
