Austin, as far as running goes, he's right that bodybuilders don't run. Keep in mind what "bodybuilder" means, it most definitely doesn't mean "staying physically fit and being as healthy as possible". Being "physically fit" requires cardio, most any sport does as well, but that's not bodybuilding.
A101 is completely right about running. In fact, cardiovascular activity is more important than lifting weights. Period. Bodybuilders don't do it because they take drugs.
This is a bodybuilding discussion though, not gym class fitness tests.
On another side note, No Xplode does work, without a doubt, it's caffeine and arginine, those things both increase stamina while lifting. It's JUST caffeine and arginine though, all this talk about No Xplode "cycles" and the like is laughable and tells me you might be buying into the marketing of "No Xplode's gonna make you fuckin huge bro!" a little too much. It's caffeine and arginine, it works. It's not roids, BSN has no "magic" formula, you can get those 2 ingredients cheap if you like their effect on your workouts.
Austin, good to know you're seeing results but up to 3 hours in the gym 5 times a week is never a good idea, even if you're on roids that's a pretty outrageous amount of time and tells me you're not lifting heavy. Heavy as in, heavy for you, DIFFICULT.
