You need to overcome something. Most guys began toiling over their bodies to compensate for some weakness. I was short, and to hit on girls I hit the weights. Weight lifting has a real shallow learning curve. You get good fast.
Exercise is the skill for the hopelessly unskilled.
You're a good man who sets goals. Either you go to the gym, or you suck. You have problems to solve. In my own life of 35 years, I have spent more than 18,000 hours working on my body, building biceps the size of babies' heads and spraining my share of ankles. I wonder what I could have done with that time, what great things I've escaped doing.
