As promised, here’s my routine for heat stretching that proved successful for a while.
Make a heat sock with a large sock filled with about 1lb rice. Close the end with stitching or a tie wrap. I nuke this in the microwave for 2 mins.
Stretch our your unit and cover with the sock. At first it may be too hot to keep on for more than a few seconds. Repeat until you can feel that the heat is transferred deeply. This is usually around 2 mins for me.
Remove the sock and stretch as hard as is tolerable. Hold for around 30 seconds or until it becomes uncomfortable.
Repeat the heat/stretch cycle until there is insufficient heat in the sock. As the sock becomes cooler it is possible to press the sock harder against the skin to transfer more heat. There comes a point where you can press the sock hard enough without discomfort and actually use it to grip your unit and stretch while the heat is still applied.
I do little more than a straight forward stretch. Sometimes I pull in a circular motion – slow enough to feel the burn in isolated areas.
I finish up with the Jes extender to hold in an extended position while cooling off. Some say that actively cooling may help also, though I have never tried this.
The above gave me 6/16th in 6 days before an abrupt halt in progress. I started this routine yesterday after a layoff of more than 1 month in the hope that it is repeatable. I do not know the answer to this yet.
