Coach's biceps tendon prep is well known.
However, I was curious if there is anything in the Foundation Series which is in the same vein of Coach's bicep tendon prep, but only for other joints.
The principle seems to be that you are putting a stretch on the tendons/muscles at the joint and at the same time it takes strength to hold yourself in the position.
I have the whole series, but I'm not sure if anything counts for what I'm asking.
What do you think?
