On exercise and recovery.
I try to move every day. Currently, I’m in the gym every other day. I tend to do a full-body workout, but when I get bored or plateau I’ll switch to a push/pull/legs type routine.
On non-gym days I’ll run, ride, or take a long walk. I also run and ride very slowly.
I’ve run myself into knee operations in the past so I focus on not getting injured rather than speed. Recovery is critical for that goal, so I’ll have periods of much lower intensity. My favorite recovery treats are a massage, infrared sauna, and magnesium baths.
To put it bluntly, rest days are more important than training days.
