I don't know that it is an intense routine, it's what works for me though.
As far as the X4 and X40, neither of them were purchased for price, I bought them for quality and longevity. Both products are well made for what they are. I just decided that for the time I have to dedicate to this, those products at the time seemed to be the best options.
I am trying to get a full year out of the X4 , but it is starting to become uncomfortable since my shaft is rubbing on the adjustment screws and on the wide girth base inside edge. Since there is no other available wide girth base I will probably switch to hanging at some point.
The BM X40 is great for its simplicity and able to grow with you, plus if used correctly feels great too.
I have no reason to not use it, especially after many hours in the extender. Is it better than other pumps? I have no clue, it was the first pump I ever purchased just based on many different reviews on several different "PE" sites.
On a side note, I had to add another set of 13mm bars to the extender recently. I am pretty excited about that since the last few weeks to a month I was "in between" on the extender vs tension. Since adding the bars, I have lost a little bit of time since fatigue sets in much quicker but well worth it. As the weeks progress this new set of rods will be much more tolerable.
I am currently stretching to 21.1 cm. for about 3.5 hours a day. Same deal, 5 on and 2 off.
Till measurement day!
