Neuroscientist Reveals the Best Exercise for Growing New Brain Cells
Neuroscience has discarded the “adult brains can’t grow new cells” belief in the face of evidence to the contrary. Weight lifting triggers BDNF (Brain-Derived Neurotrophic Factor), promoting neural growth. This may help shield you from cognitive decline and lower your risk of Alzheimer’s.

Retraining Gait Pattern as Effective as Medication for Relieving Knee Pain
68 adults with mild-to-moderate knee osteoarthritis. Each participant received motion-capture analysis to determine a personalized gait modification—adjusting their foot angle 5 to 10 degrees inward or outward. This wasn’t a one-size-fits-all fix; some people needed to toe-in, others toe-out. Those who followed their prescribed foot adjustment reduced knee pain as much as common NSAIDs like ibuprofen. Even more impressive? MRIs showed the improved walking led to slower cartilage deterioration, and biomechanical analysis revealed a 26 percent greater reduction in the damaging forces that stress the knee joint. It’s simply a matter of adjusting biomechanics to make your movement work for you. Every step you take sends 2 to 4 times your body weight through your knees. Changing your foot angle shifts this force away from the worn-out cartilage and onto healthier areas—kind of like avoiding a pothole on the road. The destination is the same, but the route causes less damage. Check out Pop! Running for an expert on gait modification.
