The Fun Theory

A simple, inexpensive and direct idea to make people more active during ‘dead’ times. Think of all the wasted time you spend commuting, stuck in traffic, buses and trains... Springs can be replacing handles or hang together with them, also they could be attached to the bus walls and will be accompanied by fun messages that invite people to try them out. You could also use special strenght-measurer handles, (already existing in the market), to make it more fun!
