Aerobic gardening

I haven't worked out at the rec center all week, but today I indulged in some aerobic gardening, digging up a chunk of ground for a new raised-bed herb garden and then helping my daughter plant a butterfly-and-hummingbird garden in front of the house. The muscles I've developed on the rowing machine all semester helped me dig up the rough, rocky soil where we'll relocate the herb garden, and I did enough bending and stooping in the flower garden to give the abs a decent workout, but tomorrow I'll be sore all over...which will give me an excellent excuse to sit out in the sun and admire the flowers. Come on, sunshine! I'm ready to rest.
