which exercise is likely to target the abdominal muscles? (5 points)

c squats
d jogging

Explanation:

First Question (Jamie's Workout)

To improve muscular endurance (like abdominal endurance), the principle is using lower resistance/weight with a higher number of repetitions. Option a: higher resistance + fewer reps is for strength, not endurance. Option b: lower resistance but decreasing reps doesn't help endurance. Option c: higher resistance with increased reps is not typical for endurance (endurance uses lower resistance). Option d: lower resistance and 12 - 18 reps (high number) matches endurance training principles.

Crunches are specifically designed to target the abdominal muscles. Lunges target legs (quadriceps, hamstrings), squats target lower body (glutes, quads), and jogging is a cardiovascular exercise that works multiple muscles but not primarily abdominals.

Answer:

d. Use lower resistance or weight and a high number of repetitions, 12 to 18 repetitions per set.
