If you are going to improve in any way at the gym you have to be someone who likes pain, or at least does not mind it much.
Now I am not talking here about some kind sadistic or masochistic perversion.
This is about enjoying the struggle of physical feats.
You might be pushing through the pain of a run looking for a second wind, or dead-lifting three reps of previous maximum weight.
I personally enjoy the soreness the day after a big weightlifting workout.
You hurt a little bit and your muscles twinge with the memory that you have been active.
Let’s all be more active, ok?
“More stress?” I didn’t like the sound of that. AT ALL! “Yes. More stress. We are going to push you harder—the hardest you’ve been pushed in your workouts—and we will do a workout specifically based on stressing your pull-up muscles to smash this plateau and get your pull-up numbers increasing. Be ready for a good workout tomorrow morning.” “Good? What do you mean by good?” I asked, worried that Uncle Jake’s definition of the word good might be a little different than mine. “I guess I mean pain. Be ready for some pain in the morning.” That’s EXACTLY what I was afraid of!
