Final answer:
The resting heart rate is recommended to be measured at the radial artery in the wrist, according to NASM.
Step-by-step explanation:
The National Academy of Sports Medicine (NASM) recommends measuring the resting heart rate at the radial artery, which is located in the wrist.
While the radial artery is the preferred location, the resting heart rate can also be measured at other pulse points on the body, including the neck, ankle, and other superficial arteries.
It is important to note that a variety of commercial electronic devices are available to measure pulse as well.
