Which version of you would have done better at something like... running around with your kids at the park? Or running a mile to catch a train?
My main point is that defined abs and a giant chest and arms have little to do with health and performance, but the body-building culture has convinced us all that they do. It got ridiculous in the 90s when Arnold and Stallone were portrayed as heroes good at everything due to their big muscles, when the reality was that Arnold needed help wiping his own ass when he was at his biggest.
But if your goal is attracting a mate or intimidating other males bench press and bicep curls are your path.
I am also coming from a place as someone who hit 315 on bench in my mid 20s but felt like an old man.
