30 Minutes After Exercise
Golden Time for Body Condition Care
After running or high-intensity exercise, muscle use causes a rise in skin temperature and leaves behind subtle tension and swelling. If this condition persists, the body easily feels heavy, and recovery time before the next exercise becomes longer.
What is needed after exercise is not strong stimulation, but reducing heat sensation and recovery care that awakens the flow again.
