Do them seated, and when they get tuff just stand up and bust a few cheats out using a little momentum. Not a ridiculous amount though.
I swear some kids around my gym do them so horribly. For example, this one kid, hes probably 17,18 years old, I see maybe twice a week depending on my schedule. I've seen him grab the 30lb dumbbell and loaf it up sideways one at a time, his form is so bad he gets stared at. For one, who does side laterals one at a time, the only great I remember doing them like that was Katz and his form was pretty spot on. This was ridiculous though.
