I agree with you. Going hard day in and day out in this manner is not even possible for myself. I go hard but I do not go hard all the time. That is the reason it is important to balance rest and recovery when doing girth work (according to SRT).
For example: I have now done 3-4 days extremely hard, but to gain I now need to let my tissue rest a bit (expanded and elongated) for at least 1 day. If I would do this intensity day in and day out without resting my tissue, my penis would stop working (no erections), and I would probably also stop gaining.
@kriskros I would recommend you to find the sweet spot for gaining (active pe and passive/recovery pe).
There is also a thing called:
overworking the tissue. This can happen both with length work and girth work.
1 session per day, or 2 days on 1 day off can be more then enough for you to promote/induce growth.
