Muscle, Bone & Functional Preservation During Weight Loss

Resistance training largely preserved fat-free mass during dieting in a controlled 16-week study of older women; another study of 123 adults averaging 72 found supervised HIIT preserved lean mass over six months, with modest changes that do not establish strength or functional benefits. Recent practical GLP-1 and body-recomposition guides offer manageable training suggestions but little evidence or programming detail; DXA lean mass is not synonymous with muscle.
