You really think after a lifetime of training anyone else is going to know my body when to push it when to rest what it can and can't do and how well it can recover better than me?? Training is not about planning everything in advance you have to listen to your body feedback and adapt somedays you can train for hours other days you need to sit in a rocking chair eat drink and sleep 16 hours and rest
Today I surfed for an hour then I went for a 2 mile walk on the beach. I will lift for an hour tonight. I am in sick shape I don't need a damn trainer. What are they going to tell me work out 3 hours a day instead of 2? Are they going to count my reps and hand me my weights motivate me to show up at a gym? I have a gym in my house and plenty of motivation I am doing several hundred reps a workout right now.
Your response is exactly why it is a good idea for you to have a trainer or coach. However, you probably wouldn't take their advice because you have clearly already decided you know more than everyone else. What did you hope to gain from starting this thread, which you titled "Critique review condition and size at 43"? It sure doesn't seem like you wanted to be critiqued or reviewed. Why? Because you reject all advice. It seems more like what you want is people to applaud you.
Yes, you know your own body. Yes, you have years of experience. Yes, you look great for a person of any age. And yes, everyone including you benefits from feedback. Why? Because without it, we lose perspective.
