Need to build strong neck...

[KelJu]

Get a towell and fold it length wise. Then place it on a wall infront of you, and lean forward, placing your forehead on the towell(supporting your body with only your head/neck). Then 'roll' from side to side. If your not strong enough, use your hands for support, and once thats too easy, move to the floor.

I had to do that during my years of football. It never hurt me but I never felt any improvement from it. We did it with our helmets on, and by grabbing our facemask for balance.

if you are a chic, give more aggressive head! I can be your training partner

My gym doesn't have any machines for the neck and I don't have a neck strap.
So what I do is improvise. While laying down on a bench I place a dumbell on my head and procede to go up and down.

I thought this was a good idea.
