HIIT intensity is typically near maximal, eliciting what percent of peak heart rate?

Explanation:
High-intensity interval training works by pushing the heart into a near-maximal effort during the intense bouts. That near-maximal zone is typically around 80 to 100 percent of peak heart rate. Training at this level quickly stresses the cardiovascular and anaerobic systems, promoting improvements in VO2 max, speed, and metabolic adaptations. Rest periods let heart rate recover enough to repeat the hard push. Lower intensities, like 40–60 percent, are considered moderate and wouldn’t elicit the same HIIT adaptations, while 20–40 percent is quite light. Brief moments at 100 percent can occur in some all-out sprints, but the common HIIT target is the high end of the HR max range (80–100%).
