With 48,900 businesses in the U.S. in the category of fitness, gym, and health clubs in the U.S, there is enormous potential for using the members to raise funds for charity while getting more fit.
One opportunity is a "weigh off" with the help of an organization, Weigh to Give, that sets up the whole program. This works much like a marathon, where participants are sponsored for the pounds lost. The money raised can be donated to any of the charities that Weigh To Give, gives to, or the business can recommend a charity they would like to donate to.
Up until now charities have been using weigh offs for their fundraising, but this is a great way for small businesses in the health field and fitness industry to give to charity in a way that aligns with their business purpose.
