As you all know by now the state of New York has issued a required closing of a majority of businesses including fitness facilities. It is imperative that we abide by this requirement to do our part in preventing the spread of Coronavirus (COVID-19) any further. For this reason, Definitions is closed indefinitely as of 8pm on 3/16/20. We will continue to keep you informed the best we can as new developments arise that influence our status of business.

Please take care of yourselves both physically and mentally during these challenging times.
