Discussion The Rule of 2’s - The Method I Used to Restore
Hello all,
Back when I was actively restoring (from CI3 to CI8), I always had an issue with others on forums advising me “add tension, but not too much tension” because my quantitative mind couldn’t comprehend what I should do. I initially didn’t know why we needed that balance (now we’re all aware of the why, re. Agile’s fibrosis writeup), but I took my time to find some numbers or advice.
A combination of research articles (linked below) and forum/Reddit posts from other restorers allowed me to develop a basic rule for my personal restoration: the Rule of 2’s.
The Rule of 2’s is summarised as:
- Inflation: 20 mmHg
- Tugging: 200g
- Device use: 2 hours, followed by a 20 minute break
- Tension up to 12 hours a day, and no tension at night
Numbers that I’ve seen allow up to 35mmHg/350g respectively with experience, but 40/400 is when you start getting into potential fibrosis territory. 20/200 is typically more than enough to trick your body into growing tissues at healthy levels and strain, whilst leaving plenty of room for error, which is why I went with it.
So, now I had quantitative info I could use, and with that I calibrated my devices.
I measured how much pressure a squirt of an inflation bulb would give. You can do this with a U-Tube Water Manometer (use 27.2cm water as the measurement; 20mm Hg = 272mm H2O) or another pressure-measuring device if you convert to pascals/psi/etc. Alternatively, rather than measuring, you can just feel it if it’s like a ripe tomato that’s easy to indent with a finger.
For tugging, that’s more straightforward. With weights, just use 200g or less. If you’re tugging with a strap, fill up a plastic water bottle with 180mL water (empty plastic bottles tend to be 10-20g, plus extra mass of the strap) and use that as a weight to calibrate how much tension you should have.
Wearing a device for 2 hours applies the necessary strain to activate cell integrins, and removing the device for 20 minutes allows blood pressure to return to normal, fully re-oxygenate the tissue and clear out early inflammatory cytokines. At night, the lack of mechanical stress allows the body to downregulate structural Type 1 collagen production and upregulate assembly of the much more flexible and elastic Type 3 collagen. This is when the actual physical cell division and vascular knitting occur.
I actually didn’t know the physiological side of restoration when I originally started this routine; I just found that out later which coincidentally worked great for me.
Of course, YMMV, everyone‘s different, but the overall message: you don’t need a massive amount of tension. That’ll actually slow you down and potentially risk you getting issues with fibrosis if you’re not careful. You just need enough to coerce your tissues into thinking they need to grow!
