Explanation: 

Detailed explanation-1: -Your radial pulse can be taken on either wrist. Use the tip of the index and third fingers of your other hand to feel the pulse in your radial artery between your wrist bone and the tendon on the thumb side of your wrist. Apply just enough pressure so you can feel each beat.

Detailed explanation-2: -place your index (first finger) and middle fingers on their wrist, at the base of their thumb. using a clock or watch that counts seconds, count how many beats you feel in a minute, or count them over 30 seconds and multiply the number by 2 to work how many beats a minute.

Detailed explanation-3: -press the first (index) finger and middle finger of your other hand on the inside of your wrist, at the base of your thumb – don’t use your thumb as it has its own pulse. press your skin lightly until you can feel your pulse – if you can’t find it, try pressing a little harder or move your fingers around.
