You train your muscles. What about your bones? A new BMJ review of 124 randomized trials in 18,429 adults 40 and older found brisk walking or jogging linked to favorable bone density results at the lumbar spine, femoral neck, and hip, plus benefits from combined aerobic and resistance training at the spine (Lu et al., BMJ 2026;394:e100561). Certainty was low to moderate, so this supports staying active as we age, not a guarantee against fractures. Track activity alongside nutrition with KetoNoir. This video uses AI-generated equipment visuals and voiceover with an original locally synthesized score at 80 BPM. The KetoNoir screen is real with example data, it is not a bone-density measurement, and the study did not test KetoNoir.
