Researchers believe that exercise helps to boost the immune system and increase strength, thus resulting in fewer incidences of absenteeism due to sickness or injury.

Corporate wellness programs tend to improve overall morale, as participating employees feel better both about themselves and their companies.  Such programs lead to a more energetic, positive, and productive workplace, thus strengthening a company and helping to position it for success.  Healthy employees work better, and in turn, provide gains for the company.

Because of financial concerns, companies often struggle with the decision to invest in a fitness or wellness program for their employees.  No decision-maker would deny that "one has to spend money to make money", as the familiar saying goes.  Once the initial investment is made, the program will immediately start paying for itself - provided that it's properly promoted and maintained - and, eventually, realize concrete savings for the company.  Healthy employees make healthy companies, which are likely to bring in healthy profits and that, in itself, is a positive return on investment.

Healthy employees are happy employees.  And those who are happy workers almost always turn out to be faithful, long-term employees.  So the healthier and happier a work force, the less a company has to spend on hiring and training new personnel.  The basis for creating a healthy work force, of course, is a well-conceived and well-promoted corporate fitness program.
