Is this a safe way to work the neck muscles?

I put a 25lb weight on my head with a towel underneath and rock my head back and forth. Is this safe?


sometimes I'll get a iron type taste in my mouth...like the taste of blood, but little soreness.Is this a safe way to work the neck muscles?
nope, you will wear down cartilage.


Have you ever done shrugs?


hold a barbell at your waist with a comfortable weight, raise your shoulders and come up onto your toes at the same time. Just be careful not to roll your shoulders, it's the equivalent to sliding your face across asphault.
