First, congratulations on working with a company that has a fitness center onsite. I agree with the professionals who have already responded to this question. Here are a couple of ideas on corporate health and fitness from the ÔÇÿvault’ for you.
You didn’t mention if your facility was ‘unionized’ if it is I have found that meeting with union reps in one large meeting is a great way to increase daily participation and increase volume.
Work with all of your c-level and department leaders e.g. human resources, finance, legal, operations and payroll; involve each department leader in the internal marketing component to bolster employee participation. I find that meeting with administrative support teams to spread the word is equally beneficial in building the numbers.
Payroll adding a memo on employee paystubs is a great way to remind employees every Friday to use the fitness facilities. HR including fit tips from you in the employee newsletter.
Working with the company aggregate demographics and health risks identified through your HRA you may craft a good employee ÔÇÿpoll’ asking employees which health/fitness programs or contests they would participate in when offered.
