Today was similar to last Monday, we drilled lots of newaza and then focused on Osoto Gari. I'm focusing on using good form in my Kuzushi to start with. My instructor says that it's ok if I try the first part of the throw twice so that I get more practice with breaking balance.
We're apparently being taught in the traditional way (like in kata) because in the adult's beginner's class it's unlikely that we'll be in competition so we get to focus on correct form.
I'm still having trouble letting go of my right hand when doing Osoto Gari but I expect that when I get used to the throw I'll probably fix that problem.
So far, my impression is that Judo is a very technical art in both throws and groundwork but still involves a lot of explosive power especially when throwing.
