The summer sun is a wonderful thing. But going for a run in the sweltering heat? That's not always so pleasant. If you're going to exercise when the temperature is high, remember to keep safety in mind. Try working out in the early morning or late evening, dress appropriately and drink plenty of fluids. But if you're looking to escape the heat altogether, CafeMom has some indoor workout suggestions:

At home exercise. Work out in the convenience of your own air-conditioned living room. To keep things interesting, try swapping workout DVDs with a friend or renting new ones.

Dive right in. Swimming may be the best hot weather workout there is. You can visit a local community center's indoor pool.

Video games. Try out Wii Fit. Who ever said video games weren't good for you?

Climb the stairs. If you live in an apartment building or there are multiple floors in your workplace, you've got free fitness gear at your disposal.

What's your favorite workout when it's hot outside?
