Chief? I'm honored, but undeserving.
Yeah, that's not what I meant at all, I agree natural does not mean safe. That's why it drives me nuts when companies just come up with herbal alternatives to drugs which are outlawed or which require prescriptions. I meant natural in the sense that you would not take supplements or steroids, including megadosing on select vitamins, minerals, amino acids, etc. Although natural in the bodybuilding realm usually refers to those who are not on roids, but for some reason they will still swallow anything legal to get big.
There really are some inexpensive protein powders available (or they were, I still have to find out if that company carries the stuff I bought). You have to wade through a lot of garbage to find it though. Most products have ridiculous claims, added ingredients, low quality, etc plus they cost some astronomical amount.
The stuff I bought was cheap, I forget how much it was now since I bought a huge bag of it over half a year ago. I'll have to look but I think it was maybe 30-40 dollars for 15 pounds or something like that. Anyway, it was some large amount that would last me forever and cheaper than buying jugs or milk or dry milk or dry eggs, plus a higher quality protein. It didn't have any claims or requirements, just a big bunch of protein to do what you will.
So, it is out there if you look, but like you and I have said it's certainly not required just that it MAY be cheaper and of higher quality than you might get through meat, eggs, etc.
Just as you and I have emphasized, the most important part of the lifting process (aside from proper stimulation) is resting your muscles properly. Starting out I'd say a good routine may be upper monday, lower wednesday, upper friday, lower sunday, etc just for an example. Once you get into it a little more you can decide to rest less or more. Arms don't normally require as much rest as chest, legs, back, etc but they are also worked often indirectly so it all works out. Some say to allow 2-3 days for arms, 3-4 maybe 5 for chest back, maybe 3-4 for shoulders and 5-6 for legs, but others view it differently. Just have to listen to your body and make sure you get enough rest.
