Apr 1, 2026
Dr. Vonda Wright, orthopedic surgeon and musculoskeletal expert, shares concise tips on boosting bone density with impact and resistance work. She explains how much jumping matters, compares weighted vests to plyometrics, and highlights pelvic floor concerns that should not sideline women. Practical cautions on ramping up training and spotting overtraining are discussed.

Episode notes
Jumping Drives Bone Density Through Fluid Dynamics
- Jumping produces fluid dynamics in bone that stimulate osteoblasts to build bone density.
- Vonda Wright's study of masters athletes found highest bone density in jumping sports like volleyball and basketball versus swimming or cycling.
Do Short Multidirectional Jumping Sessions
- Do multidirectional jumping to reach 3.5–4 times body weight, which is needed to stimulate bone growth.
- Aim for either 10 minutes of multidirectional jumping three times weekly or ~50 jumps daily split into sets like hopscotch.
Weighted Vests Add Cardio Load Not Impact
- Weighted vests increase workload and heart rate but usually don't create the high-impact force bones need.
- Vonda uses vests to raise workload ~10% during treadmill sessions but says 8-inch steps can already deliver ~4x body weight impact.
