This study investigates the impact of four standard of care, monitored group exercise regimens (resistance training) on conditioning and hypertrophy in women previously treated for breast cancer. The study will compare two conditioning regimens (6-12-25 and 8x8) and two hypertrophy regimens (5/5/5 cluster sets and double training) to assess changes in VO2 max, muscle mass, and fat mass.
