I dont see how this many people discourage working out after blazing, unless they only tried it a handful of times no more than a week's worth. Me, I don't feel right doing my semi-daily workout without preceding it with a bowl. Plus it does make it go by faster, and the runner's high combined with the cannabis high is primo, almost like an opiate. I also puff afterwards. After you get in the habit, you don't crash so much as just feel relaxed and tranquil inside.
If you find it hard to workout after puffing, workout before puffing. But give it at least 2 weeks for it to become habit, then smoking will sort of set off a bell that makes you want to get real active, then you can truly relish the workout, and you'll have more energy throughout the day and not burnout like most stoners. I drink yerba mate tea for added energy.
I'm primarily concerned with cardiovascular health so I do 30 min. on the elliptical combined with push ups and situps, 5-6 times a week. Before I had the elliptical I did jogging in place or walking in a hilly area or dancing to music, anything sweaty.
Don't smoke cannabis to relieve anger, but rather as a reward for working soberly through anger.
Life is too entertaining for higher powers not to be watching closely.
A rule really only needs to be followed by those who do not know why it is a rule.
