Work out for free while 'paying it forward'

PORTLAND -- Beast Fit Nation in Portland is offering an unusual incentive, offering free workouts to anyone who "pays it forward."

Owner Sergio Jones came up with the idea for the nation's first free fitness club. Members don't pay a membership fee of any kind, but are encouraged to "pay it forward" through random acts of kindness.

Since the gym opened in March 2012, they have had 2,500 people participate in the free fitness club.
