exersize?

ok it has been 3 weeks since i have smoked (21) days for the people who are baked right now..and i want to know what exersizes i shoudl do to make sure it is out of me..becaus emy friend told me running just burns water weight or something..compared to lifting weights...any ideas or suggestions?..and what else can i do to surely pass my test?

if you smoke some weed you come up with some better ideas man! like getting someone to piss in a bottle or something lol

Cardio. Anything to increase your metabolism. Drinking water doesn't hurt either. Lots of people will say it doesn't help unless you do it the day of the test, but drinking water DOES increase your metabolism, which means it'll get out of your system faster.

You should be clean already though. I pissed clean after 18 days of abstaining.

In fact I think I might have pissed clean after smoking the night before a test and simply drinking lots of water (but only pissing once or twice before the test, 3 hours before it)
