I have a very curious question....as some of you may know already, I am a new guy and I've just restarted my training from a ten year break. I restarted about 1 month ago and when I started I was also on the Atkins no carb diet. I was very disciplined and ate less than 10g of carbs a day for at least 3 weeks. Anyway, during my low carb period, no matter how hard I trained, I never had any post workout soreness in my muscles the next day....no a bit! I recently came off the Atkins diet and have been consuming calories and carbs like a fiend for max growth....now I hurt the next day????? Why???? I know that there is a physiological explanation for this and I know this is the place to get the answer. On a sidenote: during my low carb time, my exercise intensity did not decrease so I have ruled out inability to train as hard without carbs. Why the burn with carbs, but no burn without???? Thanks in advance. I have become more in touch with my body's needs by reading this site for a week than I had in the last 30 years of guessing.
