There are many that suggest "gravity is a vertical force", which is true, and that "it only acts downward", which is also true. But then they say "gravity can't help you move forward". This I contend is not true. Without a full physics analysis considering all the forces present it is not possible to determine [...]

Many have noticed that day to day times, distances or other running statistics are rarely posted here. It is not that I don't like numbers, it is just that my health goals usually have little to do with them. One goal I do like to set and measure is consistency. One way to measure consistency [...]

A previous post (The Physics of ChiRunning, Lean ... Analysis) with a physics analysis suggested you can use the external force of gravity to your advantage. Doing this adds the concept of a "controlled fall" to your running gait cycle. You can get the feeling for this concept in just a few moments as described [...]

The ChiRunning concept that seems to be most referenced is that of a subtle forward lean forward to aid in propulsion. There are challenges in the subtle forward lean position (Blog Post: ChiRunning Common Challenges, Lean) and there are challenges implementing other concepts to support overall balance. One very important supporting concept is relaxation; and [...]
