PROSPECTUS SUPPLEMENT NO. 4

(to Prospectus dated January 19, 2024)

(Interactive Strength Inc.)

Up to 4,284,146 shares of common stock

This prospectus supplement supplements the prospectus dated January 19, 2024 (the “Prospectus”), which forms a part of our registration statement on Form S-1 (No. 333-276466). 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 February 16, 2024 (the “Current Report”). Accordingly, we have attached the Current Report to this prospectus supplement.

This Prospectus and this prospectus supplement relate to the offer and sale, from time to time, of up to 4,284,146 shares of the common stock, par value $0.0001 per share (the “common stock”), of Interactive Strength Inc. d/b/a Forme (the “Company,” “Forme,” “we,” or “us”) by the selling stockholder, Tumim Stone Capital, LLC (“Tumim” or the “selling stockholder”), or its permitted transferees or other successors-in-interest. The shares being offered by the selling stockholder may be issued pursuant to the common stock purchase agreement dated December 12, 2023 that we entered into with the selling stockholder (the “Equity Line Purchase Agreement”). See “The Equity Line Transaction” in the Prospectus for a description of the Equity Line Purchase Agreement and “Selling Stockholder” in the Prospectus for additional information regarding Tumim.

The selling stockholder, or its permitted transferees or other successors-in-interest, may offer and sell the shares of common stock described in the Prospectus from time to time in a number of different ways and at varying prices, including through public or private transactions at prevailing market prices, at prices related to prevailing market prices or at privately negotiated prices. We provide additional information about how the selling stockholder may sell the shares in“Plan of Distribution” on page 187 of the Prospectus. The selling stockholder is an “underwriter” within the meaning of Section 2(a)(11) of the Securities Act of 1933, as amended. The selling stockholder will pay or assume discounts, commissions, fees of underwriters, selling brokers, dealer managers or similar expenses, if any, incurred for the sale of the shares. We will pay the expenses (except brokerage fees and commissions and similar expenses) incurred in registering the shares, including legal and accounting fees. See “Plan of Distribution” in the Prospectus. References to the “selling stockholder” in the Prospectus shall also refer to any permitted transferees or other successors-in-interest to the selling stockholder.

We are not offering any shares of our common stock for sale under the Prospectus and will not receive any of the proceeds from the sale of shares by the selling stockholder. We are registering the offer and resale of the shares to satisfy contractual obligations owed by us to the selling stockholder pursuant to the Equity Line Purchase Agreement and documents ancillary thereto. Our registration of the shares covered by the Prospectus does not mean that the selling stockholder will offer or sell any of the shares.

If the 4,284,146 shares offered by Tumim under the Prospectus (including 502,791 shares of common stock we agreed to issue, no later than the trading day immediately following the effective date of the registration statement of which the Prospectus forms a part, to Tumim as consideration for its irrevocable commitment to purchase shares of our common stock under the Equity Line Purchase Agreement, and 3,781,355 shares we may sell to Tumim under the Equity Line Purchase Agreement from time to time after the date hereof) were issued and outstanding as of the date hereof (without taking into account the 19.99% Exchange Cap limitation as discussed elsewhere in the Prospectus), such shares would represent approximately 23.0% of the total number of shares of our common stock outstanding (and approximately 33.3% of the total number of outstanding shares held by non-affiliates) as of

September 30, 2023. Any of the shares subject to resale hereunder will have been issued by us and acquired by the selling stockholder prior to any resale of such shares pursuant to the Prospectus.

Our common stock is listed on the Nasdaq Stock Market under the symbol “TRNR”. On February 15, 2024, the closing price of our shares of common stock was $0.68 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.

This prospectus supplement updates and supplements the information in the Prospectus and is not complete without, and may not be delivered or utilized except in combination with, the Prospectus, including any amendments or supplements thereto. This prospectus supplement should be read in conjunction with the Prospectus and if there is any inconsistency between the information in the Prospectus and this prospectus supplement, you should rely on the information in this prospectus supplement.

See the section entitled “Risk Factors” beginning on page 12 of the Prospectus and in any of the documents incorporated by reference in the Prospectus to read about factors you should consider before buying our securities.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement or the Prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

Item 3.02 Unregistered Sales of Equity Securities.

As previously disclosed, on August 22, 2023, Interactive Strength Inc. (the “Company”) received written notification (the “Notice”) from the Nasdaq Stock Market (“Nasdaq”) that the Company’s stockholders’ equity as reported in its Quarterly Report on Form 10-Q for the period ended June 30, 2023 (the “Form 10-Q”) did not satisfy the continued listing requirement under Nasdaq Listing Rule 5450(b)(1)(A) for the Nasdaq Global Market, which requires that a listed company’s stockholders’ equity be at least $10.0 million (the “Stockholders’ Equity Requirement”). As reported in the Form 10-Q, the Company’s stockholders’ equity as of June 30, 2023 was approximately $5.0 million.

In October 2023, the Company submitted, in a timely fashion, the required compliance plan to regain compliance with the Stockholders’ Equity Requirement. One aspect of this plan was that the Company would apply for a transfer from the Nasdaq Global Market to the Nasdaq Capital Market and rely on the $2.5 million Equity Standard on the Nasdaq Capital Market under Listing Rule 5550(b)(1) (the “NCM Equity Requirement”).

The Company successfully transferred its listing to the Nasdaq Capital Market on January 26, 2024.

Nasdaq accepted the Company’s plan and required the Company to demonstrate compliance with the NCM Equity Requirement by February 19, 2024.

On February 15, 2024, the Company issued 2,377,258 shares of the Company’s Series A Convertible Preferred Stock, par value $0.0001 per share (“Series A Preferred Stock”), to four accredited investors (the “Series A Holders”), each of whom was an existing investor of the Company, upon the conversion of certain outstanding promissory notes with a then-outstanding aggregate amount of approximately $4.3 million (the "Debt Conversion"). The shares of Series A Preferred Stock were issued pursuant to an exemption from the registration requirements under Section 4(a)(2) of the Securities Act and Rule 506 of Regulation D promulgated thereunder. Each of the Series A Holders is an “accredited investor” as defined in Rule 501 under the Securities Act. Neither the Series A Preferred Stock nor any shares of common stock issuable upon conversion thereof has been registered under the Securities Act and thus such shares may not be offered or sold in the United States in the absence of an effective registration statement or exemption from the registration requirements of the Securities Act.

The Series A Preferred Stock is subject to certain rights, preferences, privileges, and obligations, including voluntary and mandatory conversion provisions, as well as beneficial ownership restrictions and share cap limitations, as set forth in the Certificate of Designation of Series A Convertible Preferred Stock (the “Series A Certificate”). The Series A Preferred Stock can be issued at any time and, subject to certain exceptions as set forth in the Series A Certificate, any subsequent mandatory or voluntary conversion into common stock shall be at a conversion price at least equal to or above the closing price per share of our common stock as reported on the Nasdaq Stock Market on the last trading day immediately preceding the date that the Series A Certificate was approved by the Company’s board of directors, subject to customary adjustments for stock splits and combinations. The description of the Series A Certificate herein does not purport to be complete and is qualified in its entirety by reference to the full text of the Series A Certificate, which was previously included as an exhibit to the Company's Current Report on Form 8-K with the Securities and Exchange Commission on January 8, 2024.

As a result of the Debt Conversion, approximately $4.3 million of liabilities on the Company’s balance sheet was converted into equity.

As previously disclosed, on February 2, 2024, the Company completed the acquisition of substantially all of the assets (and the assumption of certain liabilities) of CLMBR, Inc. and CLMBR1, LLC (the “Acquisition”). As a result of the Acquisition, the Company increased its stockholders’ equity by approximately $4.5 million.

As of February 15, 2024, as a result of both the Debt Conversion and the Acquisition, the Company believes it has regained compliance with the NCM Equity Requirement.

If the Company fails to evidence compliance with the NCM Equity Requirement in its Quarterly Report on Form 10-Q for the period that will end on March 31, 2024, the Company may be subject to delisting.

This Current Report on Form 8-K, including this Item 3.02, shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of these securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such jurisdiction.

These forward-looking statements are subject to risks and uncertainties which may cause actual results to differ materially from those expressed or implied in such forward-looking statements. These risk and uncertainties include, but are not limited to, the following: the Company's ability to regain or maintain compliance with the stockholders' equity requirement or other listing compliance standards of Nasdaq during any compliance period or otherwise in the future; that Nasdaq will grant the Company any relief, including any extension or grace period, from delisting as necessary or whether the Company can ultimately meet applicable Nasdaq requirements for any such relief; risks related to the substantial costs and diversion of personnel’s attention and resources due to these matters; that the Company has incurred and expects to continue to incur significant losses; our ability to achieve or maintain profitability; our future capital needs and ability to obtain additional financing, which may not be available, to fund our operations; the growth rate, if any, of our business and revenue and our ability to manage any such growth; risks related to our subscription or any future revenue model; our limited operating history; our ability to continue as a “going concern”; our ability to compete successfully; fluctuations in our operating results and factors affecting the same; our reliance on sales of our Forme Studio equipment; our ability to sustain competitive pricing levels; the growth rate, if any, of our target markets and our industry; the ability of our customers to obtain financing to purchase our products; our ability to forecast demand for our products and services, anticipate consumer preferences, and manage our inventory; our ability to attract and retain members, personal trainers, health coaches, and fitness instructors; our ability to expand our commercial and corporate wellness business; unforeseen costs and potential liability in connection with our products and services; our dependence on third-party systems and services; and risks related to potential acquisitions, intellectual property, litigation, dependence on key personnel, privacy, cybersecurity, and other regulatory, tax, and accounting matters, and international operations, as well as the risks and uncertainties discussed in our most recently filed periodic reports on Form 10-Q and subsequent filings and as detailed from time to time in our other SEC filings. Given these risks and uncertainties, you should not place undue reliance on these forward-looking statements.
