3. Carefully push one end of the drinking straw into this blob so that it sticks upright from your wrist.

Your pulse rate gives the general health of your heart rate. The throbbing pressure bulges of the pulse travel through all of the body’s arteries. The wrists are not the only places where you can feel them. The radial artery lies just below the skin and directly above the wrist bones.
There are several other sites where the pulse can usually be felt clearly, especially after you have been exercising.
Other pulse sites:
The neck, the crook of the elbow, the groin, the back of the knee, the front of the ankle.
