You Trust a Piece of Equipment With Your Body. Tzumi Exploited That Trust.

Adjustable dumbbells are not a luxury item for most people who own them. They are a home gym substitute. They are what you buy when you cannot afford a gym membership, or when the gym closes, or when you are building something for yourself in your garage or your spare bedroom. They are the answer to the question: how do I take care of my body on my own terms?

Jason Martinez bought his FitRx SmartBell XL in Yonkers, New York in 2023. He bought it because he thought Tzumi was a quality company. He bought it because the product had good technological features. He bought it because he believed it was safe and reliable. None of those beliefs were false through any failure of his own. They were false because Tzumi built a product with a mechanically unsound weight-securing mechanism, kept that knowledge inside the company, and kept cashing checks.

Think about what it means for a weight plate to dislodge mid-use. You are mid-lift. Your muscles are engaged. Your form is set. You are not braced for impact. A plate weighing anywhere from a fraction to a significant portion of the total dumbbell load drops. Depending on the position of the dumbbell at that moment, that plate drops on your foot, your shin, your knee, your face. The 60-plus incident reports in the CPSC recall database are not abstractions. Each one is a specific moment when a real person’s body absorbed something they had every right not to absorb.

Seven people in those reports were documented as injured, with bruises, contusions, and abrasions recorded. Those are the people who reported it. The complaint does not claim those seven are the only people hurt. They are the people who bothered to file a report with a federal agency, which is a level of civic effort most people never take after an injury.

Beyond the physical, there is a quieter kind of harm. Martinez now owns a piece of equipment with a recall on its record. When he tries to sell it, he will disclose that history or he will not, and either choice costs him something. He has spent hours, and will spend more hours, participating in Tzumi’s recall process, which the lawsuit argues does not even promise to fix the underlying problem. That is his weekend, his evenings, his time, extracted from him by a company that chose profit over a safer locking mechanism.

The machinery of consumer capitalism runs on the assumption that companies will warn you before selling you something that can hurt you. When that assumption breaks down, the harm flows quietly. It flows into people who are just trying to get stronger in their own homes.

What the Lawsuit Actually Says: Verbatim From the Court Record

The following are direct quotes from the class action complaint filed March 28, 2025, in the United States District Court for the Southern District of New York. Case number 7:25-cv-02578.

“Specifically, the Class Dumbbells’ Weight plates can dislodge from the dumbbell handle during use, posing an impact hazard to consumers.” Complaint, Paragraph 4

• This is the core defect stated plainly. The mechanism that holds the weight plates to the handle fails. The plates fall. The failure mode is not theoretical; it is the confirmed basis for a federal recall.
• The complaint frames this as a design defect, not a random manufacturing anomaly. That framing matters legally: a design defect means every single unit shares the same flaw, not just unlucky batches.

“To date, there have been more than 60 reports of weight plates dislodging during use, which have been linked to at least seven injuries, including bruises, contusions and abrasions.” Complaint, Paragraph 22 (citing CPSC Recall Notice)

• Sixty-plus incident reports on a 12,400-unit product is not a rounding error. That is a pattern of harm that was documented, public, and growing before the recall date of March 20, 2025.
• The seven confirmed injuries represent the lower bound of harm. The complaint does not claim seven is the total number of people hurt; it is the number who were formally documented. Many injuries from dropped weights go unreported.

“Defendant’s Recall, which includes a free fix-and-repair clause requiring Defendant to repair and replace the faulty parts, does not offer any reasonably foreseeable guarantee that the Dumbbell Defect will go away permanently. Rather, the Recall mentions installing a new dumbbell handle and storage tray, but mentions no testing or assurances that such repairs will solve the issue fully.” Complaint, Paragraph 24

• This is the lawsuit’s most damaging argument about the recall itself. Tzumi’s proposed remedy replaces the handle and tray. The complaint argues the root cause of the defect lives in the design of the adjustable mechanism, and a new handle does not fix a flawed design.
• Tzumi provided no testing data, no engineering assurance, and no third-party validation that the replacement parts eliminate the plate-drop risk. From a legal standpoint, the complaint frames this as offering the appearance of a remedy without the substance of one.

“Defendant manufactured, marketed, and sold the Class Dumbbells under the guise of these Dumbbells being safe and operable. Instead, Defendant sold Dumbbells with defective components that present serious safety risks. And rather than refunding or reimbursing Plaintiff and Class Members the difference in resale value, Defendant has offered to simply replace the Class Dumbbells’ defective components with other likely defective components without fixing the root cause of the Defect.” Complaint, Paragraph 47

• “Other likely defective components” is the phrase doing the heaviest legal work in this paragraph. The lawsuit is alleging that Tzumi’s recall fix installs replacement parts that may carry the same fundamental design problem. This is not a routine complaint about a slow recall process; it is an allegation that the remedy itself is defective.
• The refusal to offer monetary compensation for lost resale value is separately identified here as a harm. Owners who received a recall notice and participated in the repair process received no payment for the fact that their product is now permanently worth less on the secondary market.

“Defendant knew of the falsity of the safety of the Dumbbell Defect and/or recklessly disregarded the truth or falsity of the dangerous nature of the Dumbbell Defect. Defendant intended for Plaintiff to act upon such falsity as part of Defendant’s commercial operations to sell Dumbbells.” Complaint, Paragraph 55-56

• This is the fraud allegation. “Recklessly disregarded” is legal language with a specific function: it establishes that even if Tzumi claims it did not know with certainty, it had a duty to find out before selling and failed to meet that duty.
• “Intended for Plaintiff to act upon such falsity” alleges that the marketing and sale of the dumbbell as a safe product was not an innocent omission. It was the mechanism by which the sale was made. The complaint argues the concealment was structural to the business model, not incidental to it.

Who Gets Hurt When a Company Decides Safety Is Someone Else’s Problem

Public Health

The physical harm from this defect is concentrated in moments that are supposed to be safe. Home workouts carry an implicit promise: you control the environment, so the risks are yours to manage. Tzumi’s defective product broke that promise.

• The CPSC recall documents seven confirmed injuries including bruises, contusions, and abrasions. These injuries resulted from sudden, unexpected plate separation during normal use, precisely the kind of harm a consumer has no ability to anticipate or prevent.
• The 60-plus incident reports represent a documented public health signal that went unaddressed through the product’s entire commercial lifespan before the recall. Consumers reporting harm to no effect is a public health failure in addition to a corporate one.
• Adjustable dumbbells ranging from 10 to 90 pounds cover a wide spectrum of load. A plate dislodging at the higher end of that range creates the potential for serious orthopedic injury, particularly to extremities and feet, that the complaint’s current injury list may not yet fully capture as more reports come in.
• The lawsuit alleges the recall remedy does not guarantee the defect is eliminated. If the replacement handle and tray carry the same underlying design vulnerability, the public health risk continues after the recall, not just before it.

Economic Inequality

The people most likely to be harmed by this defect are the same people who had the least power to protect themselves from it, those who bought a home gym alternative instead of a commercial gym membership and had no ability to inspect the internal mechanism of the product before purchase.

• Walmart.com was the exclusive retail channel for the FitRx SmartBell XL. Walmart’s customer base skews toward working-class and budget-conscious households. The population disproportionately exposed to this defective product is people who were stretching their dollars for fitness equipment, not buyers who could afford premium or professionally certified alternatives.
• The resale value of every recalled unit is now permanently diminished. A dumbbell with a known recall history fetches less money on the secondary market. Owners who paid full price for a product Tzumi misrepresented as safe are now holding an asset worth less than what they paid, with no compensation offered beyond a parts swap.
• The recall process itself imposes a time cost. The complaint notes Martinez has spent hours, and will spend more hours, managing Tzumi’s recall. That time burden falls on people who cannot easily absorb uncompensated administrative labor, particularly those working hourly or multiple jobs.
• The aggregated class claim exceeds $5 million under the Class Action Fairness Act. That figure represents money extracted from consumers who were told they were buying a safe, functional product, spread across at least 12,400 household budgets that have each absorbed a loss they did not consent to.

The Scale of the Class, in Numbers

Every Legal Angle the Lawsuit Is Pursuing Against Tzumi

The complaint stacks seven distinct legal theories. Each count is a separate avenue for damages and each one points back to the same conduct: Tzumi knew, did not tell you, and kept selling.

• Count I: Unjust Enrichment. Tzumi accepted money for a product it knew was defective. Retaining that money without providing a safe product is unjust enrichment. The complaint demands restitution.
• Count II: Fraud by Omission / Fraudulent Concealment. Tzumi had a duty to disclose the defect. The complaint alleges it actively concealed it. Punitive damages are sought on this count, meaning the court could award more than the actual harm to punish the conduct and deter repetition.
• Count III: Strict Liability, Failure to Warn. Regardless of intent, Tzumi was the manufacturer and had a legal duty to warn. It did not warn. Strict liability means intent is irrelevant; the failure to warn is itself the violation.
• Count IV: Strict Liability, Design Defect. The design of the adjustable mechanism is alleged to be unreasonably dangerous. The complaint specifically notes safer alternative designs existed that did not have this problem, meaning Tzumi had options and chose not to use them.
• Count V: Negligent Failure to Warn. Even if strict liability standards are not met, Tzumi’s failure to warn fell below the standard of care any reasonable manufacturer owes consumers. Negligence is a lower bar, and this count provides an alternative path to damages.
• Count VI: Negligent Design Defect. Tzumi had access to industry knowledge, safety data, and consumer complaints. It either knew or should have known the design was dangerous. Choosing to continue selling despite that knowledge, or failing to investigate when it had reason to, is negligence.
• Count VII: New York GBL Section 349. New York’s consumer protection law prohibits deceptive acts in commerce. Tzumi marketed and sold dumbbells represented as fit for ordinary use when they were not. Every New York buyer in the class has a separate state-law claim under this statute.

If You Bought a FitRx SmartBell XL, Here Is What You Can Do Right Now

Every one of the 12,400 recalled units sold through Walmart.com represents a potential class member with legal standing. The following steps are specific and actionable.

Regulatory Watchlist: Bodies With Jurisdiction Over This Conduct

• CPSC (Consumer Product Safety Commission): The CPSC issued the March 20, 2025 recall. File your own incident report at SaferProducts.gov if you experienced plate dislodgement or injury. Every filed report creates a public record that strengthens the class and informs future enforcement.
• FTC (Federal Trade Commission): The FTC has authority over deceptive advertising and marketing claims. The complaint alleges Tzumi marketed the FitRx SmartBell XL as a safe, high-quality product while concealing a known defect. Consumer complaints to the FTC at ReportFraud.ftc.gov add to the public record of deceptive trade practices.
• New York State Attorney General: The lawsuit includes a claim under New York General Business Law Section 349, the state’s consumer protection statute. The NY AG’s office actively pursues deceptive trade practice cases. A complaint can be filed at ag.ny.gov.
• DOJ (Department of Justice): If evidence of deliberate concealment of safety information from the CPSC emerges during discovery, the DOJ’s Consumer Protection Branch has authority to act. This is a longer-term watchlist item as the litigation develops.

Specific Steps for Class Members and Affected Communities

• Do not discard your dumbbell or packaging. Physical evidence and purchase records are critical for class participation. Retain the product, any accompanying warranty documents, and your proof of purchase from Walmart.com.
• Document any injuries immediately. If you or someone in your household was hurt by plate dislodgement, photograph the injury, seek medical attention, and retain all records. Medical documentation creates a direct damages claim separate from the economic loss claims of the broader class.
• Do not participate in Tzumi’s recall repair without legal advice. The lawsuit specifically argues the recall fix may not eliminate the defect and that accepting the repair does not necessarily waive your legal rights, but this is an area where consulting with class counsel before acting is advisable. Contact Sultzer and Lipari, PLLC or Poulin Willey Anastopoulo, LLC (both listed as attorneys for plaintiff in the court filing) for information on joining the class.
• Share this information with other FitRx SmartBell XL owners. The class is only as strong as its membership. Mutual aid here means making sure people who bought this product through Walmart.com know they have legal standing and are not alone in absorbing this loss.
• Push your local consumer protection organizations. Neighborhood consumer advocacy groups, tenant unions, and community centers that serve working-class households can help circulate recall information to people who may not monitor CPSC notices. This is especially relevant in communities where home gym equipment purchases through Walmart are common.
• Track the case docket. Case 7:25-cv-02578 in the Southern District of New York is public record. PACER (pacer.gov) allows anyone to access federal court filings. Following the docket keeps you informed of class certification decisions, settlement offers, and trial dates without depending on corporate press releases.
