DKD, this is where I would jump in and tell the beginner to be their own expert, I'm not too keen on PT's
The problem I see today is beginners idolize the champions/the gifted and cherry pick...bit here and there without really thinking about it.
I've made that mistake when I was younger and paid the price.
I've spoken to many, and still do observe older men whom are still actively training, the common theme from all of these blokes is; work hard, work brief and above all make sure it is safe.
I am so much more open minded about the Iron Game today.
After over 30 years I’ve learned a lot.
There are a LOT of things that work.
Lifting weights works! No matter how you do it! Efficiency is really the biggest difference.
Eventually, everyone will run out of gains. Then there is the safety difference. Increased danger does not mean better results.
I have friends in the Iron Game who are bodybuilders, powerlifters, athletes, weekend warriors, strength coaches, and more.
We are all brothers and sisters in Iron. We love to lift weights. I do not agree with them all obviously. But, then again, I would be stupid to think I know all the answers. If I did, I would be a millionaire because I would have figured out the “perfect routine” for gains!
Regardless of which part is dominant, (95% of us have at least one or two areas were a body-part is or appears to be developed) one must learn to exercise correctly, most importantly with the multi joint exercises, as someone once said; "Practice makes perfect; as long as you practice perfectly.* Practicing mistakes makes for perfect mistakes."
The other 4% of the population are extremely well developed, the remaining 1% are well ahead of everyone and are that way in spite of their routine, not because of it, it's why I like the quote; "you cannot make chicken soup out of chicken shit"
