With running or jogging, there's no distinction between left or right legs to stay balanced. Rollerskating and blading fall in the same classification. You point straight ahead and swing from the hips. Likewise, with the skogging technique, you develop a similar movement. Except you have a flat surface you use to "rest" one leg while the other does the work.  With most long distance skaters, it makes total sense to alternate legs out of necessity. It is also one way to get into funky sideway pushing habits that looks unhealthy and quite frankly... fugly.  But for the short runs to enhance a sidewalk surfing experience, skogging it up can make a cardio experience very desirable if not .. addicting!

What separates skogging from alternating leggers is the one foot transition flair as the switch from one foot to the other takes place. The LA freestylers during the Del Mar contests incorporated short spurts of alternating legs adding to the degree of difficulty of their maneuvers. It seems like an obvious movement for those who have the desire to add an extra degree of difficulty to their skateboard session to round out a balanced body movement exercise.

    Most kids wouldn't think twice that skateboarding is an aerobic exercise. But as the years go on, the gym may get old, the bike repetitious movement stale,  in-lines/quad skates a yawn and you could be left staring at your skateboard wishing it could be an exercise you can roll with and this is where it originated with me. In 1975,  I needed exercise like I needed a hole in the head to lose weight. I was one strong dude with very little body fat.  With all the other sports I did, being one big lean samoan muscle machine left much to my imagination for alternative exercise.  To use both legs to push just seemed like a natural selection kind of thing that was going to develop into something hopefully greater than I had ever imagined. 30 years later, still skating and using this pushing technique that seems to have originated from days of future passed.
