For experienced strength trainers, what is true about intensity and repetitions?

• A. Only high intensity and low repetitions are effective
• B. Not specified, only low intensities are used
• C. Wide range of intensities and repetitions; dependent on goals
• D. Only low intensity and high repetitions are used

Answer: (C)

The idea being tested is that experienced strength trainers use a wide range of intensities and repetition ranges, adapting them to the specific goal. Intensity, or how heavy the load is, and the number of repetitions you perform aren’t fixed for everyone; they’re chosen to drive the particular adaptation you’re after. When you push near maximal loads, you’ll typically perform few reps to build maximal strength and neural efficiency. If the aim is hypertrophy, you’ll often work with moderately heavy loads for more reps to create sufficient muscle damage and metabolic stress. For muscular endurance, lighter loads with higher reps are common to improve fatigue resistance. Experienced lifters also cycle these variables over weeks or phases (periodization) to optimize progress and recovery.

So, the statement that there’s a wide range of intensities and repetitions, contingent on goals, best captures how skilled trainers tailor programs. The other options imply a fixed or restricted approach (only high-intensity, only low intensity, or only low intensity with high reps), which doesn’t reflect how advanced training is individualized to objectives.
