I'm no where near as strong as you yet I will hit 2.5 I think as I've only been doing them consistently since mid January and I get the feelings you mentioned..pretty cool that's why I want heavier, I'm addicted. If you could point me to any good sites that would be cool.
How long have you been doing them?
You will get there man, just keep pushing and keep consistent and you will hit your goals. Me and KD are registered over at ironaddicts forums, its a pretty good site. I have been over there for years now, lots of good guys over there. I have been lifting since '08. Made a lot of bad choices, including hiring a 24hr fitness personal trainer and doing "bodybuilding" diets, etc. But if it wasn't for all of that, I probably wouldn't be here today looking on a total new page in health and wellness.
Best of luck to your goals man, let me know if you come over to the other forum, be cool to have another RP guy over there.
