Unfortunately, I tend to dislike most forms of exercise. I've been forcing myself to do a daily rotation of 50 push-ups, 50 sit-ups, and a 10-minute run recently. Hopefully I'll be able to keep up this routine in the long run or perhaps even expand it.
I actually do enjoy taking walks, though. I find them to be quite relaxing, particularly if the weather is nice and I can find a quiet area to walk through. The problem with this form of exercise, though, is that it is quite time consuming, and I've been finding myself with very little free time on my hands as of late.
