Fitone,
I agree with you about too many people obsessing over their looks. Those cover models are paid to look like that and it isn't easy. Most of the models don't train their legs because they need to make sure they look right in pants for certain adds. I am in my 40's and functional strength is high on my list of priorities. Muscles can look good without being strong, but how does that help you in everyday life. I do care what I lift, because it is a challenge to do more and their is great satisfaction in setting a
PR. I never obsess about missing days, because this is a lifelong program and a few weeks or days don't matter much in the scheme of things. I believe you should always strive to improve, but a sense of perspective should be included in choosing your goals.
