Running form, decoded.
Evidence-based guides on cadence, gait analysis, overstriding, and using AI to actually improve your stride.
Knee Drive Drills: How to Improve Power and Reduce Overstriding
Knee drive is the link between fast turnover and a strong stride. Here are the five drills that build it.
Arm Swing in Running: Why Symmetry Matters More Than Speed
Arm swing affects cadence, balance, and energy use. Here is what good arm swing looks like and how to fix asymmetry.
Vertical Oscillation in Running: What Is Healthy and How to Reduce It
Vertical oscillation measures how much you bounce when you run. Here is what the science says about ideal ranges and how to lower it.
Heel Strike vs Midfoot vs Forefoot: What the Research Actually Says
Foot strike pattern is one of the most debated topics in running. Here is what 20 years of biomechanics research says about heel, midfoot, and forefoot striking.
