I read a quote from Dan John once. It said:
“In a group of five workouts, I tend to have one great workout, the kind of workout that makes me think in just a few weeks I could be an Olympic champion, plus maybe Mr. Olympia. Then, I have one workout that’s so awful the mere fact I continue to exist as a somewhat higher form of life is a miracle. Finally, the other three workouts are the punch-the-clock workouts: I go in, work out, and walk out. Most people experience this.”
After the initial progress you make as a new lifter, and even the relatively quick progress you make in the more “intermediate phase, progress stalls. It doesn’t stop, but it’s not as fast as it was.
Learn to embrace the routine of punching the clock. Don’t expect your progress to continue unabated forever. Enjoy the process of training. It’s better than the outcome.
