Ringside Wrap Around Neck Strengthener - 8lbs.

You can avoid using a harness on your head with weights hanging on a chain until your neck gets super strong. Better to start with 3 or 5 pounds if you've never worked your neck before. Comfortable to keep it on for long periods, you can do other stuff while wearing it. Velcro strap adjusts the size for a good fit. It will stay on when you tilt your head. The weight part is rolls of small lead shot, so it feels soft when you squeeze it. The cloth material is tough, it's not going to tear or break open. It's hand washable, brushing with soap and water won't damage it.
