  • Having not consistently engaged in resistance training 2 or more days per week over the past 3 months

  • More than 90 days since initiation of first- or second-line endocrine therapy in combination with 1) a CDK4/6 inhibitor, with or without HER2-directed therapy, or 2) a CDK 4/6 inhibitor in combination with a PI3K inhibitor, in the metastatic or locally advanced.
