New stopping point, new pace- advice needed.

JosieRawr

Ok so I'm going through something new...(new for me) my lungs are no longer my stopping point(I'm 25, but I've been a regular smoker since b4 it was legal).... I don't quit running when they(my lungs) start screaming...I don't stop half way through my work out because I can't breath.. they haven't really been screaming at all, or at least is so much less defined than when I was smoking that I just don't recognize it...

So my problem is, I don't really know when I should stop, or maybe I don't know how to really push my body to it's max, instead of my lungs' previous max point. I know it gets mediocre at some point... I just don't really notice. I'm really working on my endurance since my muscles should be the stopping point, but...I'm not feeling the omg I need to stop now...

I am doing 30ds every other day, in addition to walking/jogging with my daughter and our large pup and doing zumba(kinects) at home. I also visit the gym for yoga(aiming for 2x week, but I just started), resistance training(cybex machines and dumbbells ranging 10-20lb), swimming(aiming for 2x after yoga, but just started), HIIT on arch trainer.

This probably makes no sense, but if anyone knows what I'm talking about, tips, advice, please.

Any ex smokers who quit smoking and started working out at about the same time?
