Osteoporosis / low bone densityDo thisStrongRCT / trialHigh-impact, weight-bearing exercise (hopping, jumping, skipping, running) is a top osteogenic stimulus: daily hopping raised femoral-neck BMD via ground-reaction forces ~3x body weight. Low-impact activity (swimming, cycling) does little for bone.High-impact exercise & femoral-neck BMD (Allison 2013) (opens in a new tab)
Osteoporosis / low bone densityDo thisStrongRCT / meta-analysisHigh-impact, weight-bearing exercise (hopping, jumping, skipping, running) is a top osteogenic stimulus: daily hopping raised femoral-neck BMD via ground-reaction forces ~3x body weight.
