Just want to ask the older guys like myself a question about PR's. When you are training and wanting to hit a PR, is the PR an all time best or what? I will be 49 years old next month and when I'm training and wanting to hit a PR it is getting so hard to do so. I know what all of my all time best PR's are from 1990 to present and use this as my guide. It is very hard to beat a PR from when I was at my peak about eight to tens years ago and some even longer than that:help. Do you reset your PR's by age, weight class or what?
