There's really not an athletic bone in my body.  Exercise does not come easily to me - honestly, I'm happy to sit and read or sit and people watch.  I'm not really wired to need to move.  But when I exercise I feel good.  My thoughts are clearer, I walk taller, I have more energy.  My rolled up mat and weights sit under the sofa to remind me of the endorphins I'm always so happy to choose while Luke naps and Viv is in quiet time.  These days I can't get enough Physique 57.  I smile and sweat through the DVD (I really love it) and use any leftover time before Luke wakes up to do what I do best - sit (sweaty and endorphined up).
