the only issue is that if you misinterpret the moves and you continually practice them wrong (not generating power correctly, not having proper structure etc.) then you will be doing yourself a disservice. especially whe you will have to unlearn your bad habits and relearn them correctly. or even if you understand them correctly and you think you are doing them correctly it doesnt mean you are. its like when i first started doing deadlifts. i thought i was doing them right, just like the pictures in the book but then i had someone watch me doing them and i was arching my back, i thought i was being so careful not to but it turns out i was. so its the same thing with generating effective power in a punch or kick. it feels to you like you do it the way the book or vid tells you but unless you have someone that knows what to look at you ca't be sure. once you have the foundation laid and you have hte techs established and can be sure you are doing it right then learing from books and such is ok.
