I hate the term "lifestyle" because it makes me think of random glamour shots of the athlete that add nothing to the video.
Then again, videos that are 100% skiing are boring as hell. If I see 10 tricks in a row I usually stop watching, but that's just me. The so-called "lifestyles" that illustrate some semblance of a story, no matter how abstract or rudimentary it may be, are essential to any good video. For instance, a logically arranged sequence of different camera angles showing a rider dropping, doing the trick, riding away, and maybe something silly after. If all you do is disorient the viewer by showing trick after trick like a porno highlight reel, your video will be monotonous--esoteric at best.
