It took about 2 years but I finally hit 400 on the deadlift. When I started lifting in 2012 I was super weak. I was 31, 165 pounds, no muscle. Now I am 33, 208 pounds, getting strong. I found this website learned and learned as much as I could. When I look back at my first posts to this site it hard to watch. I was clueless.
I went to a weight lifting seminar this week, got free coaching from the presenter (Josh Bryant) and made a 35 pound PR. I was not using a belt either which is rare for me. If you are new to this site, keep learning and lifting. If I can get strong anyone can. Also dont forget to eat and lift with people that are better than you. The faster you get a network of experienced lifters to lift with the better you will be.
