FOR IMMEDIATE RELEASE

LIFE TIME FITNESS ANNOUNCES SECOND QUARTER 2014 FINANCIAL RESULTS AND

NEW SHARE REPURCHASE PROGRAM

Revenue Grew 6.0%, Net Income was $29.8 million and Diluted EPS was $0.76;

Board Authorizes Company to Repurchase up to $200.0 million of Common Stock

CHANHASSEN, Minn. (July 24, 2014) – Life Time Fitness, Inc. (NYSE: LTM), The Healthy Way of Life Company, today reported its financial results for the second quarter ended June 30, 2014.

Second quarter 2014 revenue grew 6.0% to $326.6 million from $308.1 million during the same period last year. Revenue for the first six months of 2014 grew 6.6% to $638.5 million from $598.9 million during the same period last year.

Net income for the quarter was $29.8 million, or $0.76 per diluted share, compared to net income of $33.2 million, or $0.80 per diluted share, for 2Q 2013. Net income for the first six months of 2014 was $58.1 million, or $1.45 per diluted share, compared to net income of $61.3 million, or $1.47 per diluted share for the prior-year period.

The Company also announced that its board of directors has authorized a share repurchase program under which the Company may repurchase up to $200.0 million of its outstanding common stock.

“The second quarter was a challenging one for our company as we faced unexpected erosion of membership levels at some centers,” said Bahram Akradi, Life Time chairman, president and chief executive officer. “We believe the retention-focused initiatives we have previously introduced will positively affect membership levels over time. At the same time, I am pleased to report that, as a group, the five Life Time Athletic centers we have opened in 2014 have outperformed our financial expectations. Our current plans call for one additional Life Time Athletic center opening this year, and six new Life Time Athletic center openings in 2015. These openings, along with the expansion and improvement of our member-focused health, fitness, family recreation and sports programs, serve as the foundation of long-term growth for our Healthy Way of Life Company.”

During the quarter, the Company opened its first center in Des Moines, Iowa, and the sixth center in the Detroit market, located in Bloomfield Township, Michigan. Since the beginning of the year, the Company has opened five of the six planned new centers for 2014, the last of which will be in the Las Vegas market during the fourth quarter.

Share Repurchase Program:

The new program replaces a $200.0 million share repurchase program that was introduced in August 2013. Under the former program, from its inception through June 30, 2014, the Company repurchased approximately 3.6 million shares at a total cost of approximately $171.0 million. Under the new program, share repurchases may be made from time to time through open market or privately negotiated transactions. The timing of such transactions depends on a variety of factors, including market conditions, blackout periods, and the terms of trading plans, if any, established in accordance with Securities and Exchange Commission rules.

The authorization to repurchase shares terminates when the aggregate repurchase amount totals $200.0 million or at the close of business on June 30, 2016, whichever comes earlier. The share repurchase program does not obligate the company to repurchase any dollar amount or number of shares of its common stock and the program may be extended, modified, suspended or discontinued at any time.

Non-GAAP Financial Measure

This release and the related conference call disclose EBITDA, a non-GAAP financial measure.

EBITDA. Earnings Before Interest, Income Taxes and Depreciation and Amortization (EBITDA) is a non-GAAP measure consisting 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, net cash 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:
