What this trial is about
The purpose of this study is to examine the effects of resistance exercise, such as weightlifting, on retention of muscle mass and mental health in individuals taking GLP-1 RAs (an obesity medication). Resistance exercise is focused on increasing the strength of participants' muscles, such as how much participant can lift. •The duration of this study is 3 months. This includes: * Orientation session to explain study protocol, exercise program, and complete questionnaire about participants' medical history and lifestyle. * Two health assessments at baseline and at 3 months. These assessments include body composition, resting blood pressure, cardiovascular function, and muscular strength. Both the resistance exercise group and the control group will complete assessments at baseline and again at 3 months. After the 3-month period, individuals in the control group may choose to participate in the exercise training and complete the optional 6-month assessments. * Personalized resistance exercise sessions for 60 minutes per session, twice per week, for 3 months.
