Strength, mobility, sleep and nutrition after 40, from the evidence

Evidence-based fitness for people over 40, men primarily and written so women are not excluded: strength training, mobility and joints, protein and supplements, sleep and recovery, protocol first and product second. What the research says, the free routine to start with, then the gear, programs and supplements that can speed it up. Flagship: price per gram of protein and creatine and the true cost of training programs, from each brand's own pricing pages. Written from public health sources, never as medical advice.
