To clarify - What you are saying is that you want to look like you are strong rather than be strong...? I know you don' mean it in a vanity-driven way. But, consider how that sounds.
And, no one said you had to squat 1300 to be strong....in reference to your powerlifting comment. you are referencing the absolute competition-end of the strength spectrum.
You assume too much, i personally don't want to be a powerlifter... yet the powerlifting exercises that I do help me in my logn term goals, I too obviously dont want elbow/shoulder issues. I want to be upright when I'm 70 years old. I want to be strong for the sake of longevity. No ego involved what-so-ever.
I trust that you made your statement above with the intent to not sound fake so we'll let that go. I believe you.
