This prospectus supplement supplements the prospectus dated April 27, 2023 (the “Prospectus”), which forms a part of our registration statement on Form S-1 (No. 333-269246). This prospectus supplement is being filed to update and supplement the information in the Prospectus with the information contained in our Current Report on Form 8-K, filed with the Securities and Exchange Commission on January 8, 2024 (the “Current Report”). Accordingly, we have attached the Current Report to this prospectus supplement.

The Prospectus and this prospectus supplement relate to the offer and sale from time to time by the selling stockholders named in the Prospectus or their permitted transferees of up to 1,773,937 shares of our common stock, par value $0.0001 per share (the “common stock”). Our registration of the shares covered by the Prospectus does not mean that the selling stockholders will offer or sell any of the shares. The selling stockholders may sell the shares of common stock covered by the Prospectus in a number of different ways and at varying prices. We provide more information about how the selling stockholders may sell the shares in the section entitled “Plan of Distribution” in the Prospectus.

Our shares of common stock are listed on Nasdaq under the symbol “TRNR". On January 5, 2024, the closing price of our shares of common stock was $0.75 per share. We are an “emerging growth company” and a “smaller reporting company” as those terms are defined under the federal securities laws and, as such, have elected to comply with certain reduced public company disclosure and reporting requirements.
