Build a thick muscular neck like a WWE wrestler. The muscles of the neck are the weakest muscles in the body, exercising them will prevent neck injuries and gives you an attractive, muscular and healtheir look.
Long necks are attractive when they are thick. Size really matters because it makes your long neck look shorter.
HOW TO BUILD THE NECK MUSCLES
Place your forehead on a wall or a friend's palm and then push your head against it. Do this for all other positions (Right, left and back). Do 8-10 Reps for a count of 20 seconds, daily.
OR
Lay your forehead on a pillow placed on the floor, with your hands behind your back and your waist raised above the floor, move your head forward and backwards, you are working the neck muscles while supporting your weight with your neck and your toes... Be careful not to break your neck. This is not for Newbies. Do this for all other positions (Right, Left, and Back). Do 8-10 Reps for 10 head push ups, daily.
After each session, your neck will look pumped, continue the workout. Muscles dont build up instantly, they heal and multiply when you are asleep. Do not stop the exercise, unless you feel unbearable pains. Eat healthy, with lot of proteins and vitamins and avoid sugary food, to maximize gains.
