Repetitive lifting in work environments can take a huge toll on a person's body. Take warehouses or distribution environments, for example. Lifting is repeated hundreds or thousands of times every shift, leading to fatigue, injuries, and even permanent musculoskeletal disorders (MSDs) among workers. 

In fact, musculoskeletal disorders involving the back account for 38.5 percent of all work-related musculoskeletal disorders, according to the Bureau of Labor Statistics. 

The reason for such high numbers is simple: Most workplace injuries are not caused by a single bad lift. Rather, they are the result of repeated strain over time.  

As a safety manager, this is both a safety issue and an operational challenge due to the potential for missed work, reduced productivity, high turnover, long-term strain on the workforce, and more.  

So, the question becomes:   

How can you reduce injuries without slowing productivity? Let’s dive in.

Four common back injuries from repetitive lifting 

Before we get into a solution, let’s cover some common back injuries at work.  

Most work-related back injuries fall under musculoskeletal disorders. These are injuries that affect the muscles, joints, tendons, ligaments, and spinal discs. 

In environments where workers lift, carry, and move throughout the day, injuries rarely stem from a single incident. Instead, they develop gradually as strain accumulates across hundreds or even thousands of movements. 

Many of these are also considered cumulative trauma disorders (CTDs), meaning they’re caused by ongoing stress and overuse rather than one specific event. 

Here are four of the most common back-related injuries: 

1. Lower back strain 

Lower back strain is one of the most common injuries associated with repetitive lifting and overexertion in the workplace.  

In fact, lower back pain is the most common workplace injury and a leading cause of disability worldwide. An estimated 8 out of 10 people will experience back pain at some point in their lives, and it accounts for more years lived with disability than any other condition. 

It typically occurs when muscles in the lower back are overworked due to:   

• Repetitive lifting  
• Poor or inconsistent posture  
• Fatigue over the course of a shift  

While a single lift can trigger a strain, it’s more often the result of repetitive stress on the muscles over time. 

2. Herniated or bulging spinal discs 

Spinal disc injuries occur when the cushioning discs between the vertebrae become compressed or displaced. 

These injuries are often caused by: 

• Repeated bending and lifting  
• Twisting while carrying a load  
• Lifting in awkward positions  

In many cases, disc injuries don’t result from one movement alone; they develop gradually as cumulative strain weakens the spine over time. 

Unlike a simple strain, disc injuries can lead to long-term pain, reduced mobility, and nerve-related symptoms like tingling or numbness. 

3. Overexertion injuries 

Overexertion is the leading cause of workplace injuries and a major contributor to back-related MSDs.  

These injuries happen when the body is pushed beyond its physical limits, often due to: 

• Lifting loads that are too heavy  
• Repeated exertion without adequate recovery  
• Fatigue reducing strength and control  

In warehouse environments, overexertion isn’t always obvious; it builds gradually until something gives. 

4. Twisting and awkward lifting  

In real-world working conditions, lifting doesn’t always happen in ideal positions. 

Workers often: 

• Twist while carrying loads  
• Reach outside of their center of gravity  
• Handle uneven or shifting materials  

How ergonomics help reduce back injuries in lifting tasks 

In the world of safety, the hierarchy of controls helps guide how risks should be addressed, starting with eliminating hazards where possible and working down to personal protective equipment (PPE) as a last line of defense. 

That’s where ergonomics comes in. Defined simply as fitting the job to the worker, ergonomic principles in industrial work are designed to reduce exposure to risk factors like heavy lifting, bending, reaching, and repetitive motion – all of which contribute to musculoskeletal disorders. 

Ergonomic solutions don’t only improve comfort, they also:  

• Help lessen muscle fatigue  
• Reduce the risk of injury over time  
• Support more sustainable productivity 

How exosuits improve repetitive lifting on the job

Other ergonomic solutions when it comes to repetitive lifting are wearable assistive technologies, like exoskeletons or exosuits, which are emerging as a practical way to reduce strain at the source.

Exosuits are designed to actively assist movement, helping reduce the strain placed on the body during lifting and lowering tasks. The term “exoskeleton” is often used alongside exosuits, though the two technologies serve different purposes.

Instead of relying entirely on the worker’s muscles, these systems help:

• Offload a portion of the physical load during lifts
• Reduce stress on the lower back and surrounding muscles
• Support more consistent movement patterns throughout a shift

Over time, this can help reduce the cumulative strain that leads to many back-related injuries.

HexArmor® can help with SafeLift™

As organizations look for ways to reduce lifting-related injuries without disrupting productivity, exosuits like HexArmor's SafeLift™ powered by Verve Motion represent a new approach to reducing the physical demands that drive many back-related MSDs.

SafeLift™ is a soft, lightweight, powered exosuit designed to assist the lower back during lifting and material handling tasks. Unlike passive systems that rely on stored energy or rigid exoskeletons that can restrict movement, SafeLift™ works with the body’s natural motion, not against it. 

Here’s how it works: motion sensors detect when a worker is lifting, then a small motor activates to provide real-time assistance to the lower back. In real-world use, SafeLift™ can offload up to 40% of the physical effort of every lift, helping workers experience less strain and fatigue across the shift. 

But the support doesn’t stop at the suit itself. With Verve Logic, teams also gain access to motion data that can help identify high-risk movement patterns, support coaching, and help workers lift smarter over time. 

SafeLift™ is designed to address the same risk factors that contribute to many back-related MSDs, particularly repetitive lifting, fatigue, and cumulative strain.  

Key benefits include: 

• Up to 40% reduction in lifting strain: Helps workers experience significantly less strain and fatigue throughout shifts 
• Reduced stress on the lower back: Supports the muscles and spine during high-risk movements like bending and lifting  
• More consistent movement throughout a shift: Helps maintain control and stability as fatigue builds  
• Reduced fatigue and muscle soreness: Workers report lower levels of fatigue and discomfort during repetitive lifting tasks  
• Improved lifting posture and movement patterns: Helps reduce exposure to high-risk movements like excessive bending and twisting 
• Proactive approach to injury prevention: Targets the root cause of many MSDs – cumulative strain – before it leads to injury
