Manual Neck Resistance exercises?

[comp85t]

I saw a video on YouTube explaining the neck resistance exercises when you press on one side of your head and my question is how many reps/sets do you do of these? He said start with 5 reps but didn't say how many sets.

And how often would you do this exercise a week? I know there are other ways to train the neck but I work out at home with not a lot of equipment so I opted to do this.

Bump, and how long till I see results? Should I start doing each side of my neck for 12 reps and 3 sets?
