Right knee hurts. The knee that has the occasionally issue. Possibly hill sprints. Maybe just too much high intensity. Just read 80/20 training by Matt Fitzgerald. Going again to try to do that 80% super slow running. For me it's super slow. Maybe someday if I stuck with it long enough it'd get halfway fast. I recall on the treadmilll with no incline running like 10 minute miles at least, long ago at maffetone HR. And I really didn't stick with that very long. This time I'm reading while running so maybe I'll do better.

Right knee hurts just a little. Still going to play tennis this evening.... Probably going to lose to a guy I used to always beat. Just don't have the legs. Also I have something wrong with the muscle or something that lifts my right leg. Normally just bothers me when turning over when sleeping. But for the first time just now hurt when lunging forward.

I was lunging forward because I was juggling and threw it too far in front. With two or so hours of practice I can almost juggle three balls for a minute now cascade style. Well maybe 30 seconds so far. But improving fast. At first I was doing shower style not realizing how much harder that is. Also working on fountain so I can do four. Like how it makes me feel mentally. There is something neat about it. Always had wanted to do it. Really doesn't take much time. Figure with ten hours practice I definitely should be able to juggle four. Should be able to do three pretty well with another hour or so.
