Here's a tip that one of the ladies here in the forum gave us a while back. If it's raining and you can't walk, get two cans of any soup, hold one in each hand, and simply MARCH whenever a commercial comes on TV, or when you have 10-15 minutes you can do so...or if you have the time (who does?) march for 30 minutes, or whatever the length of your usual walking time.

Doesn't have to be soup either...it could be books or any other heavy object that would have the same resistance. No bowling balls, though...LOL!
