Does piyo help you lose weight?
user
Piyo is an exercise that was popular in East Asia from about the time of Christ until the end of the 19th century.  According to Google’s definition of the word, it’s an exercise where you slowly bend forward while holding your body upright, going to the maximum that you can, and then you relax.  It’s said to help with digestion.  It is probably part of the exercise systems that many people practiced in the past, although Google doesn’t seem to know any details.
