It's perfectly OK to finish a workout saying "Hell yeah, I did that!" It should build you up, not tear you down. Exercise is not punishment.
It's health and fitness. Not "diet and starve and work out non-stop until you collapse and inevitably give up".
I stand by the statement that a strength training & nutrition regimen should improve your quality of life, not stress you out.
"In a society that profits from your self doubt, liking yourself is a rebellious act." -No idea who said it first, but I like it.
