This is why it's important to trust the process. I've spent a good part of this year chasing my PR on the clean and jerk at 300lbs, but for the past 6 months I have been failing or not even getting anywhere close to it. Every single time, I just dust myself off and tell myself that I'll get it next time. Today is that time. Not only that, I hit it after 12 sets of 2 cleans and 1 jerk!
Mental tip for everybody: BELIEVE. You might not get what you're working for instantaneously, but that just makes the journey so much sweeter. KEEP ON KEEPING ON!
