Which range corresponds to the Light zone?

• A. 36-54%
• B. <35%
• C. 55-70%
• D. 71-90%

Answer: (A)

Light intensity means you’re exercising at a low effort, easy enough to hold a conversation and recover quickly. In many training scales, this sits in the low-to-mid range of effort, roughly around 36-54% of your maximum capacity (whether you think in terms of heart rate reserve, heart rate, or VO2 max). That makes the range 36-54% the best fit for the Light zone in this question, because it captures the easy, sustainable work level. The lower end (<35%) would be closer to very light or recovery work, not the targeted Light zone here. The higher ranges (55-70% and 71-90%) represent moderate to vigorous effort, which exceed what’s typical for Light. So 36-54% aligns with the intended definition of Light in this context and is the most appropriate choice.
