Hello. I would like to share with you that after one year of exposing myself of weight training, my panic attacs gonne away/or are controlled. I used weight training to train my brain to litlle by little control anxious thoughts that always started when I lifted weights (because heart beat increases with exercice, my brain were not distinguishing heart panic beat from healthy heart beat from exercice). After 1 or 2 months I started only to start having panic attacs only at the gym in a controlled way (at home or other places were I had most of them it quickly stopped :)). But I didn´t gived up, I continued in a controlled and progressive way, challeging my thoughts at the gym, and now I´m a secure person doing my exercicies and progressing exercicies like a normal person. I continue having afraid but since I can control my heart beat increasing or decreasing my intensity of training, I ´m always on a secure zone training. But the good news is that my intensity of training is increasing every month, even more that other people that are on the gym that don´t have any problems like we have. So, I´m very proud of myself :) It´s really possible for us to superate ourselves.
