Which range defines the Very Hard zone?

• A. Moderate (55-70%)
• B. Light (36-54%)
• C. Max 100
• D. Very Hard (91-99%)

Answer: (D)

Very hard is the near-maximal effort level. It sits at the high end of intensity, where you’re pushing close to your maximum capacity and can only sustain it for short bursts. In training charts, this zone is defined by very high heart-rate targets, typically around the upper end of the range. The range 91–99% of max heart rate matches that near-max, intense effort used for short, powerful intervals. The other options describe lighter work: around 55–70% is Moderate, 36–54% is Light, and a flat 100% is a maximum effort that isn’t treated as a sustained zone with a specific range.
