Blackmail in the sense of giving them money in an envelope with instructions to keep it (or donate it to your least favourite cause?) if you fail, or in the sense of an embarrassing story or picture.

Stakes shouldn't be too high, but they do need to be high enough that there is a strong preference in favour of not failing. Obviously this should be (1) someone you trust, (2) someone who would be hard to sweet-talk into non-action in the event of your failure.

2 months of regular exercise so far. :)

There is a web site that does that for you for those who don't have a nearby friend that fits the criteria. It's called http://stickk.com, created by a couple of Yale Professors. I have no connection except that I used it to start my exercise habit last year.
