This study aims to evaluate the effect of a physical exercise intervention model on breast cancer survivors and their adherence. The sample will consist of 30 women with a primary diagnosis of breast cancer. The intervention will be carried out in a highly complex oncology center in Maceió-AL, Brazil, using the FITT components of the prescription: frequency (4 days a week), intensity (aerobic part through musical beats, subjective perception scale and resistance exercises through the number of maximum repetitions), the total time of each session will be 45 minutes. The intervention arms include combined exercise training and aerobic exercise (i.e., walking). Adherence to each intervention evaluated in the 12-week intervention cycle will be measured in each session.
