I think it kinda makes sense. While you're working out, you're getting your blood and lot of oxygen flowing through your system, which allows the THC to dissipate out more. Also you're sweating out a lot of fluids, which I guess makes for an almost "detox" environment/effect in your body.

But THC is stored in fat, so I don't know if exercising affects your fat (I heard you first burn off the food already in your system, then if you burn off all that, only THEN do you start to burn off fat). Another theory is that the heavy breathing you do when exercising can expand the lungs and increase lung power and thus possibly make your lungs able to absorb more THC afterwards.

But I did definitely notice that on days I exercised, that night I got a killer high. It really is like exercising is like a mini detox. Sometimes I used to purposely work out just bc I knew I'd get a better high that night. I think I should start doing that again. I used to exercise and look forward to smoking a bowl afterwards. Smoking would be my motivation for exercising. It sounds lame, but that was the best motivating factor ever.

Anyway, it's basically common sense. If you have one stoner who just sits around all day and lives an unhealthy lifestyle, and another stoner who exercises a lot and lives a healthy lifestyle, which one do you think will have a lower tolerance?
