Seated box jumps are a plyometric exercise that targets the legs, particularly the glutes, quads, and hamstrings. To perform seated box jumps, start by sitting on a box or bench with your feet flat on the ground and your knees bent at a 90-degree angle. Explosively push off the ground with both feet and jump up onto a higher box or bench, landing with both feet on top. Step down off the box or bench and repeat for the desired number of reps.
In CrossFit, seated box jumps are often used as a conditioning exercise or as part of a high-intensity workout that includes other plyometric movements or weightlifting movements. The height of the box or bench can be adjusted to increase or decrease the difficulty of the exercise, and the number of reps and sets can be modified to suit different fitness levels. Seated box jumps require proper form and technique to prevent injury, and they are often taught by a qualified coach to ensure safe and effective execution.
