If you've ever lifted weights or been in a room with someone who does, you know there is one thing that everyone loves to do and talk about. Whether we're talking about Olympic weightlifters or powerlifters, they all love max days and hitting PRs (personal records). They love pulling heavy deadlifts and massive snatches. In other words, lifting heavy shit. It feels great, and there's nothing like that adrenaline rush. But guess what? PRs don't happen overnight or by accident. They happen because of hard work and hours spent doing the stuff no one really wants to do. In other words, PRs happen because of rep days.
