I have a confession: I hate running. I really do. Although I've always been a decent sprinter, anything beyond 400-meters was just exhausting. And when I was done with my 1.5-mile runs, my legs were usually shot.
After a couple of years of enjoying spaghetti legs immediately following squadron PT, I decided to look into different ways to move forward more efficiently. As far as acceleration was concerned, I discovered that there are basically two ways to propel yourself forward when running: Active and passive.
Now I was presented with a dilemma: I wanted to give my poor legs a break, but which do I use? Both have their advantages and disadvantages, so I had to do a little more research to find my answer.
