Knee extending past foot when lunging
Is it really necessary (from a technique and injury perspective) that your knee shouldn't extend past the knees? I have heard many coaches point this out for how it not only helps you keep balance, but also recover faster for remise/reprise opportunities. Also good for an injury perspective for not putting too much strain.
I've always had trouble with balance when lunging and many of it comes from knee overextending. If I keep my back straight sometimes it will be too straight and it leads to a leaning back motion which is bad in the middle as a saberist.
