Working out in the heat

[wendug]

We are having quite the heat wave here in Chicago, and I know lots of the US is experiencing the heat as well. I just want to hide in the AC as the heat drains my energy. I haven't walked my dogs in the last 2 days for fear that the heat will take a toll on my 15 year old dog. As soon as I let my dogs out in the backyard the old guy heads for shade and the other dog falls over in the grass and lays there like it is too hot to move. She's fine- just doesn't like the extreme heat, either! So I've been feeling so lazy the last couple of days, although I did get a workout in today.

How do you stay motivated in this hot weather? Is there a particular type of workout you like to do when it is really hot?
