My company has recently moved offices and has included a gym in the new location for use by employees.  There are standard pieces of equipment - treadmill, bike, free weights, rowing machine.  I don't have experience of compiling documentation for gym facilities as we are a construction company so I wondered if anyone has any advice on induction documents, etc.  I have all the equipment user guides and information for the main body of the risk assessment but any advice would be gratefully received.
Many thanks in advance.
