This study is designed to investigate the effect of a structured resistance training program on glycemic control, measured by hemoglobin A1c (glycated hemoglobin), in patients with type 2 diabetes (T2DM) who are enrolled in outpatient cardiac rehabilitation. The investigator will compare the experimental group receiving resistance training to a control group made of patients enrolled in outpatient cardiac rehabilitation and perform 3 aerobic exercise modalities during their sessions, which is the current standard of care.
