OP, i believe there is a saying: “45, 45, 45”. If you can do the freaking bar, then jump in there. The faster you get a meet under your belt the faster you can gain information to help you become much stronger than you are now.
I was overwhelmed (in a good way) at my first meet by how strong some of those lifters were. When I saw guys with 5, 6, 700 pounds on their backs it made my weight seem so much lighter even though it might have felt heavy for me at the time. When you SEE someone move that much weight it just makes it seem possible for you to do it one day.
In addition to that, all of the competitors I spoke with were handing out advice left and right whenever anyone asked for it. The powerlifting community is very interesting in that even though you are ‘competing’ in the same event as someone they are still willing to help you.
sparknotes: Get into a meet as soon as you can
