Since the pill that replicates all the benefits of exercise does not exist, you need to exercise to get the benefits of exercise. The benefits of exercise are worth the personal costs.

If and when someone does invent a crazy ass pill that replicates all the benefits of exercise without the effort, I'll gladly embrace it. The self-discipline-and-enduring-suffering part of exercise is just a means to an end, not a virtue in itself.
