August 21, 2026 — An incident involving Powerblock U175 adjustable dumbbells has brought significant safety concerns to light after a weight plate reportedly sheared off during an overhead lift. The incident, which occurred within weeks of the consumer purchasing the used equipment, resulted in a near-injury and revealed multiple other plates with visible cracks, prompting questions about product integrity and the safety of heavy-duty fitness equipment.
Product Details
Product: Powerblock U175
Incident Overview
The consumer purchased a set of Powerblock U175 adjustable dumbbells for $1200 from an online marketplace, approximately 50% of their retail price. The weights were described as being in perfect cosmetic condition at the time of purchase. However, within six weeks of acquisition, a critical failure occurred: one of the weight plates sheared off while the consumer was performing an overhead lift. This sudden failure caused the consumer to nearly lose balance and narrowly avoid serious injury.
Following the incident, a closer inspection of the dumbbells revealed a more widespread problem: 8 of the 20 weight plates on the set exhibited visible cracks at the point where the initial plate failed. The consumer alleges that this issue stems from a known manufacturing defect within the Powerblock company, asserting that the U175 model, designed to reach up to 175 pounds per hand, poses extreme danger due to its substantial weight and susceptibility to failure.
Safety Concerns
The reported incident with the Powerblock U175 adjustable dumbbells raises serious safety concerns, particularly given the product’s design for heavy lifting:
- Immediate Dangers: The shearing of a weight plate during an overhead lift poses an immediate and severe risk of injury. A 175-pound weight falling onto a user’s head, face, or body can cause traumatic brain injury, concussions, fractures, spinal cord damage, severe lacerations, and internal organ damage. Loss of balance with such heavy weights can also lead to falls and secondary injuries.
- Long-Term Risks: Injuries sustained from such an incident could result in permanent disability, chronic pain, and long-term medical complications, significantly impacting a consumer’s quality of life.
- Who Might Be Affected: Users of Powerblock U175 dumbbells, especially those who have purchased them secondhand or used them in a high-frequency, commercial setting. The risk extends beyond the primary user to anyone in the vicinity, including family members or other gym patrons, if a plate were to become a projectile.
- Property Damage Potential: The sudden failure and drop of extremely heavy weights can cause significant damage to flooring, other exercise equipment, and surrounding property.
The alleged presence of visible cracks on multiple plates indicates a potential systemic issue that could lead to catastrophic failure without warning, making the product inherently dangerous for its intended use.
What Consumers Should Do
If you own Powerblock U175 adjustable dumbbells, or any heavy adjustable weight system, it is crucial to take immediate safety precautions:
- Stop Use Immediately: If you observe any cracks, deformation, or signs of wear and tear on your weight plates, handles, or locking mechanisms, discontinue use of the product immediately.
- Inspect Your Product: Thoroughly inspect all weight plates for visible cracks, especially around attachment points or where plates connect. Check for any signs of metal fatigue, stress fractures, or unusual bending.
- Understand Warranty Limitations: Be aware that manufacturers often have specific warranty terms regarding original ownership and intended use (e.g., home vs. commercial). While this may affect your recourse with the manufacturer, it does not diminish the inherent safety risks.
- Contact the Manufacturer: Even if your product is outside of warranty, contact PowerBlock Inc. to report any observed defects or failures. They may offer guidance or, as in this reported incident, provide discounted replacement parts as a customer service gesture.
- Report the Incident: File a detailed incident report with the U.S. Consumer Product Safety Commission (CPSC) at SaferProducts.gov. Your report helps identify hazardous products and protect other consumers.
- Exercise Caution with Secondhand Purchases: This incident highlights the inherent risks of purchasing heavy-duty fitness equipment secondhand, particularly when its history of use (e.g., commercial vs. home) cannot be verified. Always inspect used equipment meticulously and consider the potential for accelerated wear and tear.
Manufacturer’s Response
PowerBlock Inc. provided a response to the incident report, stating that the PowerBlock Home U175 is designed, sold, and warranted exclusively for in-home use by the original purchaser.
The manufacturer noted that the consumer had communicated directly with PowerBlock prior to the CPSC report and purchased certain replacement components at a discounted price. PowerBlock clarified that this discount was a discretionary customer-service gesture and not an admission regarding the cause of the reported damage or the existence of a product defect.
Furthermore, PowerBlock stated that based on information provided to them, the subject unit was acquired used from a third party through an online marketplace and had previously been used in a commercial gym. PowerBlock emphasized that its limited warranty for this product is restricted to the original owner and to in-home use only. They explained these limitations reflect, among other considerations, their inability to verify the use, handling, maintenance, storage, or repair history of a secondhand product and the materially different conditions and frequency of use that may occur in a commercial setting. Based on the consumer’s representation that the unit was purchased secondhand after prior commercial use, PowerBlock maintained that the subject unit was outside any applicable limited warranty.
