The whole point is to measure progress. You’re the only one so far to suggest how long to wait (with no gains / poor gains) before switching up a routine: 6 weeks to 3 months.
tenatiousD: can you explain what you mean by 2% to 4% strain per session? Not sure I understand that concept.
The millimeter measurement will have some up and down from day to day but if you track enough data points over a period of time the trend will be clear if you’re growing or not. Month to month you should see clear progress, even if it’s a couple of millimeters, especially as you track more than a couple of months. This is why I said it takes 6 weeks to 3 months to see if your program is working or not.
This is how I use tracking my daily workout RG-BPFSL and strain (though I’m not an expert as I’m still relatively new to it): In October my retroglandular (RG) BPFSL mm’s before training was in the mid 160’s, ranging from 165-171. December it is in the mid 170s, ranging from 170-175. Post training has the same relative increase. So from day to day my starting length varies a bit, as does the post-training, but the overall trend is increasing.
Notably, the increase in RG-BPFSL between November and December was smaller than the month before. So it might be time for me to consider a decon break to let the tissues soften up again, even though my per session strain numbers remain on target every session (which suggests the tissues are still pliable from the work I’m doing). Or maybe there is a small quantum increase about to reveal itself (I’ve noticed increases tend in little jumps rather than linear increases) and I’ll make another little jump in the next few weeks. So my plan is to give it another month and see where I am before I program in a decon break to let things soften up again.
So that is how I use the data to see where I’m at and what is next.
Strain per session is a measure of how much elongation you got from your session. You measure before and after your length session. Take the difference in the measurements and divide by the pre-session length x 100 to get percentage strain.
For example: before the session your measurement is 170mm. After it is 176mm. 176-170 = 6mm 6mm/ 170mm x 100 = 3.5% strain.
Check out Kyrpa’s threads and Hanging with FIRe thread for more on the basis and results of the theory from the authors. Again, I’m relatively new with this style but in the three months I’ve been using it I’ve been pleased with results. Plus I like the approach of less is more, and letting the tissues soften up to keep things growing, rather than the old hanging perspective of continuously increasing time, sessions per week and weight to get results as they start to slow down.
