Come on man... lighten up. You sounds like a supplement ad in M&F.
What he's trying to say is that the initial immobilizing pain goes away. It takes a couple weeks of conditioning to get your body used to working the muscles. *EVERYONE* who goes from sedentary to active starts this way. If you are pushing yourself for muscle growth, you will still get sore, but it probably won't ever be as bad as it is in the beginning again. But the truth is that unless you have Arnold genes, you must lift to become muscular.
Diet will help too. Make sure you are getting at least 1g of protein for every pound of body weight. You can't build muscle without it. Get in clean carbs too: oatmeal, sweet potatoes, brown rice, beans, wheat bread and all the green veggies you can stomach! Eat clean, lift hard and sleep deep. You'll see a big change.
Keep your body lean, your blood clean and your mind sharp. -Rollins
