There are two groups that the participants may choose from until enrollment for the group has reached its capacity.The active arm of the study will attend 12 one-hour aquatic exercise classes and classes will be held in an indoor heated pool. There is no cost to the participants.Both the active arm and the control group (not attending aquatic exercise classes) will have 3 measurement assessments that will compare the circumference and volumetric measurement of arms, as well as height, weight and body mass index (BMI).
