80-90 degree weather is heaven to be in. The humidity sucks though. If your house bound- try cleaning house in a pair of 3 inch high heels. Your calves and thighs get really defined and sexy looking. And dance to the music-whether its from the radio, CDs, or one of the music channels that seem to take up so many of the channels on cable. house. If you have stairs- I would highly recommend going up and down them 3-4 times several times a day in addition to the normal traipsing up and down you do during the day.
I will definately add the wrist and ankle weights while I do my daily routine around the house.
