Forearm Workout Mug mug-expander
It happened! Someone implemented the idea which has occurred to everyone, but nobody wanted to implement it. For those who like to drink beer and hates to exercise, is a lazy solution. Forearm Workout Mug expander with a beer mug for the training of the hands and forearm. The mug holds half a liter of beer, so you have enough time. The only bad — soon the tension of the expander will be enough for you. I wonder if there is more taut expanders-mugs?
The value of mugs is 10 bucks.
