We thank the Too Fit to Fracture consensus panel members for their letter to the editor regarding our recent publication [1], and for the opportunity to highlight a central feature of the LIFTMOR trial. Giangregorio and colleagues suggest that we misinterpreted the Too Fit to Fracture exercise recommendations by citing their work to support our statement “it is widely held that high-intensity exercises should not be attempted by individuals with established osteoporosis”. They contend that the Too Fit to Fracture exercise recommendations encourage individuals with osteoporosis to undertake progressive resistance training (PRT) at 8–10 repetitions which they describe as high-intensity [2]. (We note that the recommendation in the original Too Fit to Fracture publication we cited was actually 8–12 repetitions [ref. 3, Table 6, p 832]). We believe the issue is not a case of misinterpretation on our part [1], rather mis-definition of the term “high-intensity” on the part of the Too Fit to Fracture team [2, 3].
