welcome! I'm new as well and everybody here has been super friendly and helpful. What I did to help get me out of a plateau was just change up my exercise routine, my body got used to doing the same thing over and over. So I changed it up, instead of running the same bike trail for the same amount of miles and time, I would go to a different trail with some hills and shorten the time and just run as fast as I can. Your body has just gotten used to your normal routine and maybe it's time to change it up or increase the intensity, esepecially since you're nearing your goal weight. Hope this helped
