The thing about working out is that it hurts. It may make you feel great after, or it could calm you and help you deal with some shit, but it hurts. It doesn’t feel great to lift kilos of weight those two or three extra reps when you’re tired and want to go home. Your muscles will be sore, your body will be drained, and that’s no picnic.
The thing about pain is that humans connect it with everything negative. Once there is a feeling of discomfort, a person’s first instinct is to pull away and shelter themselves. It is an act of self-preservation. It’s what keeps our species alive.
However, not all pain is negative. There are things that must hurt in order to be understood. There is pain that you must feel in order to become a stronger you. How weak would you be right now if not for those moments that brought tears to your eyes? How fragile would your heart be now if not for those that have broken it.
Working out, hurting yourself in order to become greater, is what allows you to evolve. The wall will crumble, the pieces will be gathered up and molded into new material, and a stronger wall will go up. You must rip, tear, and destroy yourself in order to create a you that even you can be amazed by.
There are no happy chin-ups, there are no pleasant bicep-curls. What there is, is a whole lot of pain for a whole lot of gain. You should never harm yourself.
However, if it’s progress you seek, it’ll be difficulty that you’ll meet. The top of the hill can only be reached by climbing it.
