Here is some practical applications of the cross block : Juji Uke. I am NOT using it as a cross block (I think it's a none sense to block both arms at the same hight), I am rather using it as a deflection, doble strike, and some other cool applications against, strikes, grabs, take down...
Hope you will find something usefull.
Don't hesitate to give me your thoughts about it.
All the best,
