Too high starting traction force with KR extender
I’ve had some experience with hanging SO with a pulley. This gave me a slight increase in length and greatly diminished a sideways curvature. I used 2 lbs for 15-20 minutes, 2 times a day
Now I’ve bought a KR extender and want to use it for multiple hours a day. I measured the traction force to be between 2,2 and 3 lbs. The ‘official’ extenders like andro penis and the JES extender let you start at 1,25 lbs (according to the manuals I found online). Quite a difference!
With those extenders you should only gradually build up to 2 and later perhaps 3 lbs of force.
Could I be giving away lots of possible progress by starting out at the high amount of force the KR extender is providing?
