Which of the following is an example of an exercise that targets stability in the core?

Planks are an excellent example of an exercise that targets stability in the core. This exercise requires the individual to hold a position that engages multiple muscle groups, emphasizing the core's ability to maintain a stable posture. During a plank, the muscles in the abdomen, back, and even the shoulders work in concert to keep the body aligned and prevent sagging or arching. This is crucial for developing core stability, which aids in overall body balance and can improve performance in various physical activities.

In contrast, crunches primarily focus on the flexion of the spine and target the rectus abdominis while not engaging the core in a way that promotes stability. Sprinting and jump squats involve dynamic movements that may use the core but are more centered on strength and power rather than stability.
