Final answer:
Plyometric workout challenge involves exercises that focus on explosive movements and jumping. The MOST likely exercise is box jumps.
Step-by-step explanation:
Plyometrics is a form of exercise that focuses on explosive movements to build power and strength. It typically involves exercises that involve jumping, such as box jumps, where the person jumps up onto a box and then back down, repeating the movement. Other examples of plyometric exercises include depth jumps, where the person jumps off a height and immediately jumps up upon landing, and squat jumps, where the person jumps as high as possible from a deep squat position.
So, the MOST likely exercise that Brianna's workout challenge involved would be box jumps. This is a common plyometric exercise that targets the lower body and helps improve explosive power and vertical jumping ability.
