In the latest (NSFW!) video from 4FRNT Skis, Mack Jones demonstrates his urban skiing skills while also promoting a new form of off-hill training.

Mack explains, “This past winter, I really made a conscious effort to focus on improving my overall strength through off-hill training. I focused on, and eventually specialized in, a form of strength training known by some as ‘twerking.’ To shine some light on this forgotten practice, I teamed up with 4FRNT skis to create this introductory video, featuring me demonstrating several basic ‘twerking’ techniques, as well as some of my urban skiing shots from the year. Our hope is that one day these techniques will be employed by all skiers, as their effectiveness is second to none.”
