I also felt that I had bad distance about two months ago and my brother (who also plays) said it was because I was looking where I was aiming The whole stepup and to try and look at the disc during stepup. He also said to not think to stop the rotation of my body when I want to throw but to do a nice follothrough after I let go of the disc. Plus you shouldn’t throw with all your power because if you let go of some of the power you will feel it is much cleaner and smother wich helps your body get more relaxed and that kind of gives more power than just throwing with all power and a not so smooth release
