Ive been tryin to start to do behind the neck militarys a bit more in my workout since all I hear is posative mass building with them. Now i do regular militarys and db press. But Ive been doin it for a lil while now and i cant seem to ge the form perfect. I either tap my head on a rep or 2 or I feel like im reaching back too far. I have trouble tryin to go heavy because I feel Im going to hurt myself.
