Fitness is Training and Recovery. These together bring adaptation, which is simply another word for fitness or form. Much is made of the Training portion, for this is the part I love, the making of circles. But the Recovery aspect of fitness cannot be overstated.
Athletes, when they are able, often take afternoon naps, especially when one can fit in a training episode both in the morning, and after a nap, but before night time sleep. It has been shown that HGH (Human Growth Hormone) is naturally secreted during the early phases of sleep, and also that napping in the late afternoon is the most ideal time for the body to create it. If HGH is good, more must be better.
