In regard to exercise, which of the following statements about safety consideration is correct?

Exercising during the hottest part of the day, such as 10 a.m. to 4 p.m., can increase the risk of heat illness, and exercising at 100% of maximum heart rate is not a safe general target. Therefore, “Remaining well-hydrated while exercising is best” is correct.
