Exercise that I can do outdoors--mainly running or swimming because I don't own a bike. Running is the best because I can combine being outdoors with listening to music on my iPod (I know you can get waterproof cases for your iPod, but swimming requires me to count, which requires all my concentration, so listening to music is out).
I am thinking about buying a hula hoop and doing a combo hula hoop/jump rope workout on the patio. I think that would be totally fun, but I haven't tried it yet.
In terms of strength training, my too favorite exercises are pullovers (I like to think of them as "cardigans"--hee hee, my own little strength training joke
) and straight leg dead lifts. Both are relatively easy for me, and I am remarkably lazy, so of course I like the easy exercises.
(I keep trying to appreciate the exercises that are hard because I know if they are hard, they are working, but I just can seem to get there.) I especially like pullovers because they stretch out my abs in a way that feels really good.
