Answer 1: You can differentiate your heart rate before and after exercise by taking your pulse.
Explanation:
In order to find the pulse rate, place your index and middle finger together at your wrist joint between the bone and also the connective tissue over your arterial blood vessel ,which is found on the thumb facet of your wrist joint. You would feel the pulse, then start counting the amount of beats in fifteen seconds. After that times it by 4 to get the pulse rate per minute.

Answer 2: The advantage of timing your pulse for a full minute is you get your pulse exactly beats per minutes vs an estimate.
Explanation:
Normally pulse rate is calculated for 15 seconds and then multiplied by 4. But this case may lead to inaccuracy, as the pulse rate may vary over the time period of one minute. therefore, it is best to find the number of beats per minute instead of 15 seconds.

Answer 3: The advantage of timing your pulse over a shorter period of time (especially when you have just finished exercising) is after exercise your heart rate will begin to fall and by testing, in a shorter time you get a more accurate heart rate. The more time that passes after you stop exercising, the lower your heart rate will be.
Explanation:
Usually what happens during exercise is that the blood flow increase in the body and the heart pumps more blood into the veins and hence the pulse rate increases. But once you are done exercising, the blood flow gradually slows down and heart rate also decreases to a normal speed.
