Ah, Jenn, I feel your pain. We were in an apt. for years before we got the house. Gardening is a great pleasure but a lot of pressure too, when you are super busy. So just enjoy this time with less pressures and more fun!
I just read in Cooking Light (they have a fitness section too) that researchers have found that gardening helps more with bone density (which means less chance of osteoporosis) than any other exercise. Who knew? It definitely is good exercise, and even with a huge water bottle, I swear I lose at least three pounds in sweat while doing it!
