Hi, I was wondering two things, first, I know I shouldn't be smoking at all but I just can't give it up right now? FYI, I'm talking about smoking weed not cigarettes. Now, my question is, if I just smoke on the weekends will that siriously effect my cardio helath? and second, I'm trying to lose fat right now and my cardio endurance is not that good so what would be a good beginning cardio workout for me? thanx alot.
