For example:

"As I rested for two days my body would get a reset. On Monday-sessions I would always be well rested and ready for another hard five days. And if I weren’t well rested, if my pulse was not responding as usual or if my legs felt heavier than they usually did on a Monday-session, I would take notice early. I would know that something was abnormal before it became a real issue and I would throw in some extra rest days and avoid a negative trend."
