Explanation:

Question 3

To improve strength, the principle of strength training is using higher resistance (weight) with fewer repetitions (since strength training focuses on overload with heavier weights and lower reps, while endurance uses lighter weights and more reps). Option a suggests higher resistance and 8 - 10 reps (typical for strength), option b is for endurance, c is inconsistent, d has too many reps for strength.

• Option a (Bicep curls): Targets biceps, not abs.
• Option b (Running): Cardio, targets leg and cardiovascular, not abs.
• Option c (Russian twist): A core exercise that specifically targets abdominal muscles.
• Option d (Biking): Cardio, targets legs, not abs.

Answer:

a. Use a higher resistance or weight and fewer repetitions, eight to 10 repetitions per set.
