I'll stray somewhat and tell you what motivates me to lift weights, rather than "bodybuild" specifically.
As a forenote, I do not mean to offend anyone and am open to any and all beliefs, barring ones that hurt me/my family!
My motivation is pretty primal. I like to think of how humans would live in a more natural lifestyle and the amazing capacity of our bodies.
It's often said that our intellect is what separates us from other animals, but in saying this it's easy to discredit our amazing muscular and skeletal structures.
In a nutshell, I feel like since we've harnessed the ability to strengthen our bodies, we should. Just like having an amazing mind obliges us to learn.
