Step 1 : Introduction to the question "How many muscles does a human use when taking one step forward?"
...Muscles make up more than 40 percent of a body's total weight. There are three types of muscle: skeletal, smooth and cardiac. Skeletal muscles are the ones we control and we use to carry out conscious functions. When we take a step forward, we are actually using 200 muscles. The muscles in our muscular systems enable us to carry out our daily functions, maintain our posture and circulate our blood. Source: Reference.com
