DUBAI, April 30 (Reuters) - Shareholders of Saudi Arabia's Bodymasters are talking to banks and weighing a listing of the fitness chain on Saudi Arabia's new parallel market, Nomu, sources told Reuters.

The gym brand is currently owned through a 60/40 percent split by two funds run separately by Saudi-based private equity firms Amwal Al Khaleej and MEFIC Capital.

Shareholders have been speaking to investment banks for the past few weeks, according to two sources familiar with the transaction, who spoke on condition of anonymity as the matter is not public.

The process is in its early stages, the sources said, and shareholders have not decided on a specific action.

A process to invite banks to pitch for arranging the sale was launched at the end of last year, one of the sources said.

The sources gave no details of valuation or what percentage of shares could be floated.

The Nomu market requires companies to offer at least 20 percent to the public, according to rules on its website.

Amwal Al Khaleej declined to comment and MEFIC Capital was not immediately available for comment on Sunday.

Bodymasters has 35 gyms, mostly in Riyadh but also in Qassim, Dammam and Khamees Mushait, according to its website.

The shareholders were in informal talks with four potential buyers in January last year to sell the company in a private sale, but the sources did not comment on how the talks concluded. The transaction was said to be worth 500 million riyal ($133 million).
