We dug into the research on pre-shift conditioning in manufacturing and logistics. Here is what it actually shows, and what separates a program that prevents injuries from one that just checks a box.

Here is the straight answer, before the nuance: yes, Stretch & Flex can prevent workplace injuries. But the research is equally detailed, which is not every pre-shift program’s claim, and the difference between the ones that work and the ones that waste everyone’s time at 6 a.m. comes down to how they are designed.

That distinction matters because the injuries these programs target are the most expensive ones your business faces. If you run a physically demanding operation and you are deciding whether pre-shift conditioning is worth the time it takes off the clock, the honest version of the evidence is more useful than a sales pitch. So here it is.

Why this is worth getting right

The injuries Stretch & Flex is built to prevent are not minor. They are the single largest category of workplace injury costs in the country.

According to Liberty Mutual’s 2025 Workplace Safety Index, the ten leading causes of serious workplace injury cost U.S. businesses $58.78 billion a year, more than 86 percent of the total injury bill. Overexertion involving outside sources, the strains and sprains that come from lifting, carrying, pushing, and pulling, is the number one cause at $13.7 billion. Add awkward postures and repetitive motion and you have the musculoskeletal disorders that the National Safety Council identifies as the most common workplace injuries, period. In 2024 alone, serious musculoskeletal cases accounted for an estimated 18.5 million lost workdays.

In manufacturing and logistics, this is the whole ballgame. Manual material handling, repetitive tasks, and awkward postures are the daily reality, and they map almost perfectly onto the injuries conditioning programs are designed to reduce. In the manufacturing, retail, and logistics operations where Stretch & Flex is deployed, musculoskeletal injuries account for roughly 64 percent of workers’ compensation claims, the largest single share of the loss column. So the question is not academic. Getting pre-shift conditioning right targets your most costly and most preventable losses.

What the research actually says about stretching

This is where honesty serves you better than hype, because the literature does not give stretching a blank check.

A systematic review by da Costa and Vieira, published in the Journal of Rehabilitation Medicine, examined the available studies and found mixed results: some beneficial effects of stretching in preventing work-related musculoskeletal disorders, but noted that the studies were of relatively low methodological quality. More pointedly, the authors warned that stretching performed in isolation can be problematic. If the real causes of strain, such as a poorly designed workstation or excessive force, are left unaddressed, stretching can give workers a false sense of safety and even mask the early warning signs of injury. Their conclusion was not “don’t stretch.” It was that stretching should never be a standalone fix, and that careful program design is required before implementing it.

Other reviews land in the same place. A research synthesis by Choi found that stretching alone may not prevent musculoskeletal disorders, but it does improve flexibility and range of motion and reduce discomfort, and that conditioning and warm-up play an important role alongside it. A 2023 systematic review on stretching and work-related musculoskeletal disorders concluded that stretching exercises are a useful technique for preventing and treating pain and dysfunction in the neck, shoulder, and back, and that pairing them with ergonomic changes enhances the effect.

Read together, the evidence tells a consistent story. Generic stretching, on its own, is weak medicine. The program built around it is what turns it into an injury-prevention program.

The distinction that changes the outcome: static versus dynamic

If there is one design choice that separates effective programs from ineffective ones, this is it.

Static stretching, the kind where a worker holds a muscle in a lengthened position for 20 or 30 seconds, has the weakest evidence for injury prevention and can temporarily reduce muscle power. Dynamic warm-up, by contrast, uses active movement to raise muscle temperature, increase blood flow, and rehearse the motions the job will demand. The research over the last decade consistently shows that dynamic, active preparation is more effective at preparing the body for physical work than passive static stretching. This is the same principle sports medicine has used for years: athletes do not sit in a hamstring stretch before a game; they run through active movement patterns that mimic what they are about to do.

A program that lines workers up to hold a few static stretches is doing the version with the least support. A program that moves them through active, job-specific movement is the version that works.

What separates a program that works from one that doesn’t

Across the studies and the field evidence, the effective programs share a recognizable set of features. The ones that fail are usually missing several of them.

They use active, dynamic movement. Job readiness comes from raising temperature and rehearsing movement patterns, not from passive holds.

They are job-specific. The movements mirror the actual tasks and muscle groups the shift will use, and they target the opposing muscles to offset repetitive stress. A generic full-body routine pulled off the internet is not the same as preparation built around lifting, reaching, or standing for ten hours.

They are integrated with ergonomics and risk control, not a substitute for it. This is the warning from the research made practical. Stretching cannot fix a workstation that forces a bad posture or a task that demands excessive force. The programs that reduce injuries fall within a broader effort that also addresses the underlying hazards.

They are sustained, and people actually participate. A pre-shift program at a beverage company and a tin mill, studied by Gartley and Prosser, showed promising reductions in injuries, and the authors paid particular attention to daily participation compliance because a program nobody does does nothing. The durable programs make participation easy to sustain and easy to see, with clear ownership at the supervisor level and a way to track which crews are maintaining it.

They include education and early reporting. Workers who understand why they are doing the movements, and who feel safe flagging a tweak before it becomes a tear, catch problems while they are still cheap to fix.

They are professionally designed and measured. The credible programs are built by people who understand the body’s mechanics, and they track injury rates before and after, so the programs earn their place on the clock with data, not faith.

The field evidence backs this up. A factory study by Aje, Smith-Campbell, and Bett evaluated a short, structured stretching program built for the workforce. A textile logistics center went further, combining individual movement assessment, personalized coaching to correct harmful movement, and daily active warm-up and stretching, thereby reducing workers’ risk of elbow injury. The common thread in every success is not “they stretched.” It is “they built the right program and stuck with it.”

The manufacturing and logistics reality

These two sectors are where the stakes are highest and where the design details matter most.

The work is physically demanding; the injuries skew toward exactly the overexertion and soft-tissue strains a good program targets; and the workforce tends to turn over fast. That last point compounds the risk, because new and short-tenured workers are injured far more often than experienced ones. A constantly changing crew means a constant supply of bodies that have not yet built the conditioning or the movement habits the job requires. A well-run pre-shift program is one of the few interventions that reaches every worker on every shift, veteran and brand-new alike, before the first lift of the day.

How HealthcareLive built Stretch & Flex to actually prevent injuries

This is the part the research has been pointing at the whole time, and it is how we built Stretch & Flex.

Stretch & Flex is the evidence-based version, not the box-checking one. The sessions are clinically designed and role-specific, built around the physical demands and injury vectors of more than 30 industrial job types, from assembly-line and press operations to warehouse picking, CDL driving, and retail stocking. They use active, job-specific movement rather than passive static holds, and each one is taught on screen by a certified coach, an occupational health coach, a physical therapist, or a certified strength and conditioning specialist, in the worker’s language, with modifications for anyone on restricted duty. At 7 to 10 minutes, a session fits inside the pre-shift briefing window you already run, on any break room device, with no equipment, no dedicated space, and no outside instructor to schedule.

The program is mapped to your actual injury profile. Your implementation team builds it from your OSHA 300 log and a job task analysis, so the conditioning targets the injuries you are actually paying for: low back and lumbar strain, which is about a third of industrial musculoskeletal claims, plus shoulder and rotator cuff, knee and hip, and wrist and repetitive strain. Participation is tracked automatically by location, shift, and role on a dashboard that is OSHA VPP-compatible and flags a slipping crew before the injury data does. Since research is unanimous that participation is what makes or breaks a program, this is the part that matters most, which is why Stretch & Flex programs that reach month six average 91 percent participation, well above the sub-30 percent typical of generic wellness efforts.

The results follow the design. Across HealthcareLive Stretch & Flex employers that sustain high participation, MSK recordable injury frequency drops about 38 percent in the first year and MSK workers’ compensation claim frequency falls about 44 percent, with 94 percent of workers who stay with it for a month or more saying they would recommend it. With a prevented soft-tissue MSK lost-time claim averaging around $28,000 and the program costing roughly $400 per worker a year, a single prevented claim pays for dozens of worker-years of prevention.

And when an injury does happen anyway, because no program prevents all of them, Stretch & Flex is the front end of a connected platform rather than a standalone tool. The same system routes the worker into Remote Injury Care for fast, board-certified triage and into virtual musculoskeletal care for recovery, with no referral gap and no second vendor. Prevention and care sit in one place, from before the first lift of the morning to return to full duty.

The bottom line

Does Stretch & Flex prevent workplace injuries? Yes, when it is dynamic, role-specific, consistently used, and backed by a connected care platform for the injuries that slip through. Built that way, it goes straight at your single most expensive category of loss, and the outcome data shows it: roughly 38 percent fewer MSK recordables and 44 percent fewer MSK claims in year one. A program without those features is mostly theater, and the research makes that plain.

The good news is that the difference is entirely within your control. It is a matter of design, not luck.

Frequently asked questions

Does stretching actually prevent workplace injuries? On its own, generic static stretching has weak and mixed evidence for preventing injuries. But a well-designed program built on dynamic, job-specific movement, integrated with ergonomic controls and sustained participation, is associated with reduced musculoskeletal injuries, better range of motion, and less discomfort.

What is the difference between static stretching and dynamic warm-up? Static stretching holds a muscle in a lengthened position and has the weakest evidence for injury prevention. Dynamic warm-up uses active movement to raise muscle temperature and rehearse job motions, and research over the last decade shows it is more effective at preparing the body for physical work.

What makes a workplace stretching program effective? Active, dynamic movement rather than passive holds; job-specific routines; integration with ergonomic and risk controls; consistent daily participation supported by supervisor engagement and automatic tracking; worker education and early symptom reporting; professional design; and measurement of injury rates before and after.

Which industries benefit most from pre-shift conditioning? Physically demanding sectors with high rates of overexertion and soft-tissue injury, especially manufacturing, logistics and warehousing, and construction, where manual handling, repetitive tasks, and awkward postures drive the majority of injury costs.

Can stretching replace ergonomics and safety controls? No. The research warns that stretching used in isolation can mask risk and create a false sense of safety. It works as part of a broader program that also corrects the underlying hazards, not as a substitute for fixing them.
