Fit for Business International, Inc.
10/27 Mayneview Street
Milton, Australia

Gentlemen:

        You have requested our opinion, as counsel for Fit for Business
International, Inc., a Nevada corporation (the "Company"), in connection with
the registration statement on Form SB-2 (the "Registration Statement"), under
the Securities Act of 1933 (the "Act"), being filed by the Company with the
Securities and Exchange Commission.

        The Registration Statement relates to an offering of 3,000,000 shares of
the Company's common stock, par value $.001, the resale of 1,434,006 shares of
the Company's common stock issuable in connection with the conversion of the
Company's options and 1,784,000 shares of the Company's common stock being
registered by selling shareholders.

        We have examined such records and documents and made such examination of
laws as we have deemed relevant in connection with this opinion. It is our
opinion that the 3,000,000 shares of common stock to be offered pursuant to the
Registration Statement; and the 1,434,006 shares of common stock issuable in
connection with the conversion of the Company's options and 1,784,000 shares
sold by the selling shareholders have been duly authorized and are legally
issued, fully paid and non-assessable.

        No opinion is expressed herein as to any laws other than the State of
Nevada of the United States. This opinion opines upon Nevada law including the
statutory provisions, all applicable provisions of the Nevada Constitution and
reported judicial decisions interpreting those laws.

        We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to our firm under the caption
"Experts" in the Registration Statement. In so doing, we do not admit that we
are in the category of persons whose consent is required under Section 7 of the
Act and the rules and regulations of the Securities and Exchange Commission
promulgated thereunder.

Very truly yours,

ANSLOW & JACLIN, LLP
