What range defines the Very Hard zone?

• A. 71-90%
• B. 36-54%
• C. 91-99%
• D. <35%

Answer: (C)

Very Hard represents pushing your effort at the very top end of what you can sustain. It’s the near-maximal intensity where you’re breathing hard, muscles burn, and speaking in anything more than a few words is difficult. This zone is used to drive peak performance and speed adaptations, but it can only be maintained for short bursts because fatigue and lactate buildup come on quickly. The other ranges describe lower levels of effort, from lighter to hard but not near max. So, the range that marks the extreme end of intensity is the correct one, reflecting near-max effort.
