I didn't. My doctor recommended a physio who practises her own variant of it. Onero was developed here in Brisbane. My physio not only doesn't want to pay their licence fees, but thinks their program is too restrictive. Although I have been on anastrozole for two years, my DEXA results are improving. Two gym sessions a week are enough. I don't do much walking because Chemo Induced Peripheral Neuropathy makes walking unpleasant- it's like walking on wet sand all the time.
