EXPLANATORY NOTE

The purpose of this supplement (this “Supplement”) to the definitive Proxy Statement of Interactive Strength Inc. (the “Company”), filed with the Securities and Exchange Commission on August 18, 2025 (the “Proxy Statement”), relating to the Company’s Annual Meeting of Stockholders to be held on September 26, 2025, is to amend and replace the proxy card included in the Proxy Statement. After filing the Proxy Statement, the Company discovered that, due to a clerical error, an incorrect version of the proxy card was inadvertently filed with the Proxy Statement.

If you have already returned the original proxy card or provided voting instructions, your proxy card or voting instruction will not be valid and will not be voted as directed. You must sign the new proxy card or submit new voting instructions.

Your vote is important. Please use the new proxy card distributed with this Supplement to vote your shares.

There are no changes to the proposals to be acted upon at the Annual Meeting, which are described in the Proxy Statement. Except as amended or supplemented by the information contained in this Supplement, all information set forth in the Proxy Statement continues to apply and should be considered in voting your shares.
