Weighted step-ups are an exercise that target the legs, particularly the quadriceps, hamstrings, and glutes, as well as the core and balance. To perform weighted step-ups, start by holding a weight in each hand or a barbell on your shoulders. Stand in front of a raised surface such as a bench or box. Step onto the bench or box with one foot, pushing through your heel and lifting your body up until you are standing on top of the bench or box. Step down with the same foot and repeat on the other side.
In CrossFit, weighted step-ups are often used as a strength-building exercise or as part of a high-intensity workout that includes other lower-body exercises or weightlifting movements. The height of the bench or box and the weight of the weights or barbell 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. Proper form and technique are important to prevent injury, and a qualified coach can provide instruction and guidance to ensure safe and effective execution.
