Your Bones Aren't Smart

Your bones aren't smart, so you have to be smart for them.

Your joints don't naturally articulate in the correct way.  They just move and twist and crunch together however it happens when you throw your leg out there.

Be cognizant of how your posture and gait affects your joints.  Modify as you move to get everything working in the easiest way.  I'ts a mechanical puzzle, and the clues to getting it right are how your joints and muscles feel.

For example, I often get a dull pain in my right knee after about 45 minutes of running.  One of my solutions is to change the way I point my foot as I strike with that foot.  My right foot stike looks like this as I run:

Strike pointing towards 12 o'clock.
Strike pointing towards 11 o'clock
12 o'clock
1 o'clock
12 o'clock
11 o'clock
12 o'clock
1 o'clcok
12 o'clock
Repeat

Eventually I find a strike that reduces the dull knee pain.  Sometimes this can take a mile or more.  Usually it's pointing my foot at 11:58 as I strike, but not always.

You need to be the brains for your bones.
