All aboard, next stop PR City! Or is it?
How many times have you been pumped to hit a PR on a lift, or a run, or a workout, and then not come close to that number for months?
Then been like, what the hell, I got stronger / fitter didn't I?
That's the problem with hitting a PR, it isn't necessarily indicative of progress in your training, you could have just been having a good day.
There is a difference between striving to progress in the gym, trying to get stronger or fitter, and chasing a PR.
Don't obsess over the number, it doesn't define you, it simply tells you if you're having a good day or not.
Progress is feeling better, moving better, understanding movement, being happy with your training. Chase progress, not PRs.
