I know the whole "I haven't started yet but could use some tips" is probably a broken record to some here, but as said in the title, starting isn't far off for me and some habits to get into that would make me better prepared would be useful. Size in Judo might not be much of a factor but I should note that I am presently over 280 lbs (one of my reasons for taking up Judo is to get physical exercise.). Some advice on how to throw or lock a joint may be a good start. Thanks!
