So I am trying to learn the HS Backroll as my first invert. I have only been riding two summers and due to my work schedule only get to ride about the equivalent of two weekends a month. Here are my videos of the first time I tried the backroll, The first video is the first attempt of the day and the second video is the last attempt of the day, there were 11 other attempts in between these two and overall i feel as if i progressed pretty good for one day. The first attempt i tweaked my knee and the last one just knocked the crap out of me and I have been unable to go out to try again since then. The night after this and the next day i could barely walk, no fun.
