Exercising is good for the long term, but if the U/A is 3 days away, all exercising should be avoided.

The reason is exercising burns fat cells, releasing the stored THC metabolites back into the bloodstream. From there, the kidneys filter the THC metabolites from the bloodstream and deposit them in the bladder.

For the 3 days before the U/A, you want your body to revert to "storage mode" - stop all exercising and be as dormant as possible to avoid releasing a bunch of THC metabolites into the bloodstream, which will all end up in your urine to be detected.
Burnt Toast Reviewed by Burnt Toast on . Haven't smoked in 6 weeks Actually, I have only smoked pot twice in my life and it was this summer and the last time I smoked was 6 weeks ago. I am overweight, and I know THC can stick around for a while. I tested clean on an at home drug test from Rite Aid (Lab Accurate brand)...and I've been drinking lots of water and taking vitamins...how likely am I to pass? Anything else I need to do? Rating: 5
