Once you know the BPM you should be running to, you can find the right music and create the ultimate playlist to help you maintain a steady rhythm for your runs. You could also switch up the BPM playlists if you want a more intense run (166 BPM, for example) or an easier jog (150 BPM).
In physiology and medicine, the body surface area (BSA) is the measured or calculated surface area of a human body. For many clinical purposes BSA is a better indicator of metabolic mass than body weight because it is less affected by abnormal adipose mass.
This has led to the classification of people(s) on the basis of skin color. The skin is the largest organ in the human body. For the average adult human, the skin has a surface area of between 1.5-2.0 square metres (16.1-21.5 sq ft.). The thickness of the skin varies considerably over all parts of the body, and between men and women and the young and the old.
