In my gym, there is a vibrating belt present. I haven't seen anyone using that so far in the past two months. Is it not effective in reducing tummy fat? How is this equipment used, for what duration, and what is its effectiveness? Should it be used or not?
Vibrating belts are worthless. A crock. A sham. A hoax. A useless, insulting, silly doohickey that should be shunned by all right-thinking people.
It's proper use is to be smashed underfoot or with a sturdy implement such as an ax or crowbar. Destroy it.
Instead, look into proper diet (such as Primal or Paleo eating) and exercise (such as barbells, sprints, and sports).
