Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation As of December 31, 2016, Town Sports International Holdings, Inc. (the “Company” or “TSI Holdings”), through its wholly-owned subsidiary, Town Sports International, LLC (“TSI, LLC”), operated 150 fitness clubs (“clubs”). The clubs are composed of 102 clubs in the New York metropolitan market under the “New York Sports Clubs” brand name, 28 clubs in the Boston market under the “Boston Sports Clubs” brand name, 12 clubs (one of which is partly-owned) in the Washington, D.C. market under the “Washington Sports Clubs” brand name, five clubs in the Philadelphia market under the “Philadelphia Sports Clubs” brand name and three clubs in Switzerland. We also have one partly-owned club that operated under a different brand name in Washington, D.C. as of December 31, 2016. The Company’s operating segments are New York Sports Clubs, Boston Sports Clubs, Philadelphia Sports Clubs, Washington Sports Clubs and the clubs the Company owns in Switzerland, which is the level at which the chief operating decision makers review discrete financial information and make decisions about segment profitability based on earnings before income tax depreciation and amortization. The Company has determined that these operating segments have similar economic characteristics and meet the criteria which permit them to be aggregated into one reportable segment. Beginning in the first quarter of 2016, the Company's chief operating decision maker discontinued the review of BFX Studio financial information separately for purposes of making operating decisions and assessing financial performance. Also, in the second half of 2016, all BFX Studio locations were converted to clubs, discontinuing the BFX Studio brand. Accordingly, the Company manages and reports results through one reportable segment. Previously, the Company managed and reported results through two reportable segments: clubs and BFX Studio. Certain reclassifications were made to the reported amounts on the condensed consolidated balance sheet as of December 31, 2015 to conform to the presentation as of December 31, 2016. The Company has been experiencing declining revenue from members for several years as the fitness industry continues to be highly competitive in the geographic regions in which the Company competes. New members have been joining at lower monthly rates and cancellations of members paying higher rates will continue to negatively impact the Company's results and liquidity if these trends are not reversed. In response to this, the Company initiated cost savings initiatives in 2015 that continued through 2016 to help mitigate the impact the decline in revenue has had on its profitability and cash flow from operations. In December 2015, TSI Holdings purchased $29,829 principal amount of debt outstanding under its senior credit facility in the open market for $10,947, or 36.7% of face value. On April 21, 2016, TSI Holdings settled a transaction to purchase $8,705 principal amount of debt outstanding under the senior credit facility for $3,787, or 43.5% of face value. On May 6, 2016, TSI Holdings settled another transaction to purchase $62,447 principal amount of debt outstanding under the senior credit facility for $25,978, or 41.6% of face value. All of the above purchased debt was transferred to TSI, LLC and canceled. The Company’s ability to fund operations and capital expenditures is dependent upon its ability to generate sufficient cash from operations coupled with cash on hand. The Company believes it has sufficient liquidity from a combination of cash on hand and cash to be generated from operations to fund anticipated capital expenditures and currently scheduled debt service for at least the next 12 months. Failure to maintain club equipment could lead to decreased member satisfaction and increased member attrition and could therefore negatively affect future operating results and cash generated from operations. As further described in Note 7 - Long-Term Debt, the Company maintains a senior credit facility with its lenders which contains a term loan facility and a revolving loan facility. The term loan facility carries a gross principal balance of $202,000 and will mature on November 15, 2020. The terms of the senior credit facility include a financial covenant under which the Company is not able to utilize more than 25%, or $11,250 in accordance with terms of the credit agreement, of the revolving loan facility if the total leverage ratio (as defined in the credit agreement) exceeds 4.50:1.00 (calculated on a proforma basis to give effect to any borrowing). As of December 31, 2016, the total leverage ratio was slightly below 4.50:1.00. Any new borrowings on the revolving loan facility would be pursuant to the terms and subject to the conditions applicable to borrowings under the Company’s senior credit facility, which conditions the Company may or may not be able to satisfy at the time of borrowing. The revolving loan facility is scheduled to mature in November 2018 and under this facility we have $2,851 in letters of credit that, if still outstanding, will likely need to be funded by the Company's cash. The Company continues to focus on increasing membership in existing clubs to increase revenue. The Company may consider additional actions within its control, including the sale of certain assets, club acquisitions, additional club closures and entering into arrangements with revenue generating partnerships, some of which will utilize a “shop-in-shop” concept. The Company may also consider additional strategic alternatives including opportunities to reduce TSI, LLC's existing debt and further cost savings initiatives, among other possibilities, if any. The Company’s ability to continue to meet its obligations is dependent on its ability to generate positive cash flow from a combination of initiatives, including those mentioned above. Failure to successfully implement these initiatives could have a material adverse effect on the Company's liquidity and its operations and the Company would need to implement alternative plans that could include additional asset sales, additional reductions in operating costs, further reductions in working capital, debt restructurings and deferral of capital expenditures. There can be no assurance that such alternatives would be available to the Company or that the Company would be successful in their implementation.
