Epidemiologic studies suggest that patients with breast cancer who gain weight after diagnosis have a higher risk of recurrence and death. Regular physical exercise can help minimize postdiagnosis weight gain. The objective of the study was to assess the effectiveness of a physical test for individualizing the workloads used during a fitness program. To continuously individualize the intensity of the training, a test was designed and integrated into the sessions. The test consisted in monitoring heart rate and workload during 2 bouts of cycling at moderate intensity. The workload parameters recorded during the tests were later used as reference values to plan the intensity of the next in-person training sessions. The 5 tests conducted during the 12 weeks of the intervention showed significant differences in intensity (F = 3.034, p = 0.047). Compared with the first evaluation, the intensities measured during the third, fourth, and fifth tests presented increases of 9.9% (p = 0.02), 13.2% (p = 0.019), and 17.5% (p = 0.002), respectively. A significant increase in workload with respect to body weight was observed in the physical assessment performed after the program (t = 13.2, p = 0.0001). The peak oxygen consumption with respect to body weight (peak Vo2) achieved by the subjects during the assessment at the end of the program had also increased (t = 9.72, p = 0.0001). The intensity test, introduced in the training sessions along with the physical exercise program, was an easy-to-use, practical tool for monitoring intensity. It allows an adjustment of the workload over the program period that respects the individual progression of each patient.
