Prior studies have demonstrated that blood sugar elevations after meals is associated with babies born large-for-gestational-age. The influence of the type and timing of exercise on blood sugar modulation after a meal have not been studied during pregnancy.  We propose a prospective pilot study to determine the effects of low-resistance or cardio exercise before or after a meal on postprandial glucose levels

Participation in this study is for 3 study visits over 1 week, and it will be required to complete all 3 visits.  Each visit lasts approximately 3.5 hours.   Participants are randomized (like flipping a coin) into either a cardio or low-resistance training groups. Participants will be trained on how to insert a continuous glucose monitor and will wear it through the 5 day study duration.  Body composition, health surveys, EKG, and a baseline fitness assessment will conducted during the first study visit to ensure it is safe to participate in the study. Participants will be supervised to perform either cardio or low-resistance exercise for 20 minutes. Lunch will be provided by our facility at all 3 visits and blood work will be obtained before and after the meal.
