So I used to only run, do pushups, and situps, and sometimes pullups.

i could run 2-3 miles pretty easy at a 6mph pace.

but the past 2 months ive been doing a weight program, and working different muscles groups 4-5 times a week. i've gained muscle, and i can see the results (also dieting helped).

but it seems like my cardio is suffering. i can run as fast as before, but now i can feel it takes more effort. i am more out of breath than before near the end of my runs.

what gives? does weight lifting decrease your cardio because your muscles need more blood?

any advice appreciated
