FOR IMMEDIATE RELEASE

LIFE TIME FITNESS ANNOUNCES FIRST QUARTER 2005 FINANCIAL RESULTS
Company Reports Revenue Growth of 20.4% and
Net Income Growth of 43.8% for the Quarter

EDEN PRAIRIE, Minn. (April 28, 2005) – Life Time Fitness, Inc. (NYSE: LTM), a national operator of distinctive and large health and fitness centers, today reported its operating results for the first quarter ended March 31, 2005.

     First quarter 2005 revenue grew 20.4% to $89.3 million from $74.2 million during the same period last year. Net income during the quarter grew 43.8% to $8.1 million, or $0.23 per diluted share on 35.9 million shares. This compares to net income of $5.6 million, or $0.19 per diluted share on 29.2 million shares, for Q1 2004.

     “We are pleased with our first quarter financial results, which are driven by continued execution against our fundamental growth strategies, including new center growth, membership ramp, and increasing in-center revenue,” said Bahram Akradi, Life Time Fitness chairman and chief executive officer. “During the quarter, we opened our Commerce Township, Michigan, center, which is our sixth location in Michigan and the first of six planned health and fitness center openings in 2005. We closed the quarter with a total of 40 open centers in eight states. Total memberships grew 22%, ending with more than 325,000, driven primarily by the ramp at centers opened in 2004 and pre-sale activity at five locations since the beginning of 2005. We also are pleased with our in-center revenue growth of 31% to $22.7 million during Q1 2005, which was driven primarily by membership ramp, targeted marketing programs, and new products and services. Finally, on April 15, we entered into a new $200 million, five-year revolving credit facility, which provides us with additional resources to pursue our growth strategies at attractive pricing.”

Non-GAAP Financial Measures

     This release contains a non-GAAP disclosure, EBITDA, which consists of net income plus interest expense, net, provision for income taxes and depreciation and amortization. This term, as the Company defines it, may not be comparable to a similarly titled measure used by other companies and is not a measure of performance presented in accordance with GAAP. The Company uses EBITDA as a measure of operating performance. The funds depicted by EBITDA are not necessarily available for discretionary use if they are reserved for particular capital purposes, to maintain compliance with debt covenants, to service debt or to pay taxes. EBITDA should not be considered as a substitute for net income, cash flows provided by operating activities or other income or cash flow data prepared in accordance with GAAP. Additional details related to EBITDA are provided in the Form 8-K that the Company filed with the Securities and Exchange Commission on the date of this press release.

     The following table provides a reconciliation of net income, the most directly comparable GAAP measure, to EBITDA:
