A Headstrap Fit for Hercules
"Extraordinary" will just about cover what IronMind offers for neck training.  Adjusts to fit heads from 20" to 26", very comfortable and so good-looking that you might never guess it holds over one ton.  The aluminum frame is designed for training the front, back and sides of your neck.  Either hang the weight directly from the red webbing belt, or for added convenience, use a loading pin and carabiner.  Use the center slot on the blue aluminum frame to train the muscles on the front and back of your neck; use the round holes in the frame to train the muscles on the sides of your neck.Start easy, or you can end up with some very sore muscles, and always use immaculate form--no jerky movements and always stay well within your natural range of motion.  Use a moderate weight and keep your reps in something like the 10 to 15 range.
