Building discipline by saying you're going to do something and doing it works whether you're starting a new career or breaking out of your current job, trying to save money for a future purchase or looking to retire early. Setting small, achievable goals, and then achieving them, helps you build confidence in yourself and succeed in the long run.
Although I love weightlifting, and it is a very important part of my life, I am also a busy person with many other interests outside the gym. 5/3/1 allows me to get in, get the work done and get out in a reasonable time, while still making excellent progress over the span of the year.
I was intimidated. I couldn't even put 25-pound plates on the bar to incline press. My bench was equally as awful. My squat sucked. But I stuck with it.My older sister, who was in high school, was even told that I was going to get beat up if I kept coming into the weight room. I figured a good beating was worth it; no one was going to keep me away.
