What are your exercises to relieve stutter and improve speaking?

What are your exercises to relieve stutter and improve speaking? After a talked with my mom (who, by the way, is also stutter) about my stutter, she introduced me to an exercise she used to help with her stutter: Basicly, you choose a sentence, preferably a hard one, put your hand on your throet, and as you lower your hand down your throat you blow the air to say the sentence. After more or less 15 minutes of practice my speaking actualy improved quite a lot! Are you doing exercise to improve your speaking? and if so, what are they? How frequent you do them? And how you stay consistent?
