Explanation:

First Question (Which exercise targets abdominal muscles?):

• Crunches are specifically designed to work the abdominal muscles. Lunges target legs, squats target lower body (legs, glutes), and jogging is a cardio exercise that engages multiple muscles but not primarily abdominals.

• Lauren is changing the time per lift (from 10 to 15 seconds). Frequency is how often, intensity is effort level, type is the exercise itself. Here, it's a change in time duration of the exercise hold, so it's a time change.

Answer:

a. Crunches
