Front flips

Front flips are the only part of freerunning that I feel confident in now. These videos are not good, but will serve as a comparison to how I will perform them in a few months time (hopefully). I was trying to do the ilabaca thing and flick my whole upper body down whilst straightening the legs so they are adjacent to the floor - like a right angle. Who knows why I can't do this technique?? ME!!!!: i have the flexibilty of a table. That's why, when I try the technique, I end up bending my legs when they are supposed to be straight; resulting in quite a nice front flip but NO height and landing about a metre forward from where I took off :(
I will get better at them, though.........
