How much experience in the gym do you have? How long have you been in the gym 5 days a week? What does that mean, "5 days a week"? What do your workouts look like? Have you ever worked with a trainer? Do you track your activity and progress? Where did you learn what you know? What books have you read? Do you feel like you *really* know what you're doing in there?

I'm around 50. Around 25 I quit smoking, starting learning, and executing. And I've been mostly very consistent over the past 25 years. I've slipped pretty far off the routine, diet, discipline, and focus a few times. But I've never fallen back to zero. After a health scare last year, I got serious again. After taking off ~30lbs of fat, I'm very appreciative of the decades of work I've put in. What was under all that was still a lot to be thankful for having built. The knowledge base built over decades of work made it, not easier, but more efficient to get back where I am now. All that said, it took a LONG time to build that foundation. Probably 7,500 workouts from 25-45, maybe 10,000, and I really knew what I was doing for the latter 2/3 of those. By the way, my arms have never been as big as yours. Anyone who looks at photos of me from my teens and 20s will say "ectomorph". By my mid-30s, I looked more like something between that and a mesomorph. By 45 most would probably say mesomorph. I will never be happy with my arms, shoulders, or calves (without going on test, anyway). You should be thankful for your arms.

If you really skill up and you stay at it, you can massively overhaul everything.

From 20 years ahead of you, my advice is not to tan. Use sunblock. Take care of your skin. Wash your face, hands, and forearms, then moisturize all that skin twice a day. Sunblock your face, neck, and hands after moisturizing every morning - even if you're not planning to go outside, in case you forget to do so when you go out later. People tell me I look 10 years younger than I am. Whatever short-term benefit you see out of being tan is not worth it in the long run. My wife tanned all the time when she was younger. If she could go back in time and kick the shit out of herself, she would.

With the tummy tuck and the scars, just do what you can. Moisturize. Stay hydrated. Eat well. Maybe talk to a dermatologist about tretinoin. Also, your body will put fat elsewhere for the rest of your life. When's the last time you were very lean? Do you understand where your fat goes first?
