Final answer:
A de-conditioned man who does not exercise may have a resting heart rate of about 80 beats per minute or more, which falls within the normal range for adults. Trained athletes typically have lower resting heart rates.
Step-by-step explanation:
For an adult, the normal resting heart rate is typically between 60 and 100 beats per minute (bpm). A de-conditioned man who does not exercise may have a resting heart rate of about 80 bpm or more, which falls within the normal range. However, it's important to note that trained athletes typically have much lower resting heart rates, often in the range of 30-40 bpm.
