Wow guys. Talk about straying from the TP cannon!
If you have only been PEing for 3 months I would recommend against hanging.
Since you did not tell us much about your routine I wont bother commenting on routine, but I am inclined to remind you that 3 months is a drop in the bucket for a lot of us.
Your gain plateau can ONLY be overcome by perseverance and dedication - if you want to see real gains they you better get into the “pe for the rest of my god given life” mind set. Where you will find the motivation for this is hard to say - motivation comes from within, either you have it or you don’t.
