After being informed about the study and potential risks, all participants giving written informed consent will undergo a screening to determine eligibility for study entry. At day 1, patients who meet the eligibility requirements will be randomly assigned to Arm 1(stair stepping day followed by no exercise day sequence) or Arm 2(no exercise day followed by stair stepping day sequence). At this time participants will also be familiarized with the continuous glucose (i.e., blood sugar) monitor they will wear for ten days, be instructed how to fill out a food log every day and determine a comfortable stair stepping pace. On day 10 participants will return to the lab for sensor removal and transmitter return.
