Over-training Hanging?
I am new here but I have been foreskin restoring for about 7 yrs so I am used to my cock being tugged at about 1#. I have also jelqed on and off for years and have been doing manual stretching for about a month. I purchased the Malehanger and have been hanging for the last three days, day one 3# and I could barely feel it so went to 5# on day 2 and did 3 sets 20 min on, 20 min off. No issue with soreness or morning erection, so today I did 7.5# for 3 sets 20 on and 20 off. I could definitely feel the tug today, loved it, but no soreness or issues afterwards.
So my question, I know I am supposed to stay at one weight for a week and then move up by 2.5# to avoid over-training, and that is one set per day. But I can’t find anything here that explains why? What does over-training feel like, look like, consequences, etc? I lift weight so I know how to feel muscle over-training but can’t relate that to a penis. Help?
