Hi Judy AZ is Arizona and we do have lots of dessert areas but we also have a little of everything, ex: up north. I live in around the Phoenix area and it does get pretty hot....113F this week. Today I walked in my back yard....my yard is pretty big and I have a big pool...so I walked and sprinted at my 9th level up and down my yard. Boy I got winded and tired after does 20mins, I felt it...lol I am very out of shape and don't have much endurance. Now I started a journal, is that the same as a gym log? Have a great day
