been walking uphill with my puppy...have done 1 mile roundtrip so far...and i work all day ......just seems with the heat it takes more than I have and I don't go until late fall or winter. Thanks for your support! I'm still trying to decide. I'm still very active but haven't enjoyed my trips to Disney the last 2 years from just being so very tired! (I've also lost 17 pounds as well)!!!
