Press: Chi runners poised for softer landings - NPR

"T'ai chi is all about aligning your body and keeping it aligned for efficiency," says Danny Dreyer, who invented the technique and is the founder of the North Carolina-based company Chi Running. During daylong seminars, Dreyer teaches runners how to relax their bodies so they don't have to use as much muscle power.

"I'm basically showing runners how not to use their muscles," Dreyer says.

(This is exactly how I've always intuitively run! So now there's a name and a discipline for it. I call it floating but chi running makes great sense.)
