I've loved intense exercise since long before I ever tried the herb. Once I realized the latter was going to be as much a part of my life as the former, it seemed only natural to experiment by combining the two. The results have been good and sometimes great, though not always in the ways I would have expected. The first time, I lightly hit the VG a couple of times before lifting weights at the gym. Typically, a good sober weightlifting session for me is characterized by a slowly building sense of barely-contained aggression--correlated, I'm sure, with a rise in testosterone--which reaches its crescendo in about an hour. My slight buzz severely dampened my animal anger, which you might think would decrease my ability to perform--but that wasn't the case. I counted reps, and I did at least as well on every exercise as I had previously done sober.
Here's my analysis: Though I was deprived of aggression, I was more than compensated with the gift of presence. (Incidentally, I think the gift of presence is one of the core joys of cannabis itself.) For the first time in my life, I began to experience resistance training meditatively. I no longer thought, even fleetingly, of how proud I was for getting the weights up the previous few reps, or how nice it would be once the pain was over and I could grab a protein shake. Instead, I simply existed in what I was doing. I believe I literally forgot that I had the ability to set the weights down before I'd reached exhaustion if I really wanted to. (Gives new meaning to "failure is not an option.") Later, I did many more reps of an abdominal exercise than I had previously thought possible.
The last time I worked out while buzzed, it was late at night and I was alone in my dark house. I entered the same meditative state while doing pull-ups, and was having such a good time when I reached failure that I continued the set by doing negatives, hopping to the top position and lowering myself as slowly as I could, again and again, until I was so exhausted that I couldn't even do that without immediately dropping, as if my arms were ropes.
In addition to inducing a meditative state, the herb has a way of giving a person permission to do what he'd really enjoy most--what would satisfy his deepest soul. If you honestly, deep-down *like* punishing workouts, then the herb kicks that door wide open! (It's for this reason that, although it has certainly been a boon to *my* workouts, I would not guess that it has any intrinsic workout-enhancing property. If you loathe exercise--and I don't think anyone should feel obligated to like it--then being high will probably only remind you of how much you'd rather be doing something that better speaks to *your* passions.)
Someone might have already mentioned this, but I'd be interested to hear about any perceived differences between indica workouts and sativa workouts. So far, I've had no way of knowing which strain I'm getting. I'm inclined to think that a pure sativa would rock.
