What steps could a workplace take to improve overall health and wellness?

Encourage activity: Encouraging people to be active will improve health and well being. Some workplaces provide exercise areas or gyms.

Incentive programs: I think that incentive programs like "biggest loser" weight loss challenges or a point system for the numbers of healthy activities you participate in can be great for encouraging wellness. We tend to be competitive so we can use this to help people set and achieve healthy goals in the workplace.
