Help with teching throws

So I can block all day. High, low, crossup no problem.

What really gets me is getting thrown. I am trying to improve my teching skills but am having some trouble.

Any advice for improving this part of my game? Is it a matter of teching on reaction or just predicting when my opponent is going to throw me. Or is there some sort of option select trickery involved?

Any help is greatly appreciated.

Are you playing online? Teching on reaction in laggy conditions is damn near impossible.

Yes, I play mostly online, but some offline as well.

Just use the crouch tech, LP + LK. use it when your opponent can throw, after each attack in a blockstring. You may have to press it a few times incase they delay their throw.
