Is Your Crew Warming Up Before Work — And Why Does It Matter More Than You Think?

Most employers in construction and industry have safety programs that cover fall protection, hazard communication, and equipment operation. Fewer have a consistent answer to a much simpler question: what do you do in the first five minutes of every shift to protect your workers' bodies from the physical demands of the day ahead?

Musculoskeletal disorders — MSDs — are among the most common, most costly, and most underappreciated injury types in the construction and industrial workforce. They don't usually make headlines. They don't happen in a single dramatic moment. They accumulate quietly, shift after shift, until a worker can't do their job. And for many employers, they're showing up on injury logs without a clear prevention strategy in sight.

The answer isn't complicated. A structured stretch and flex routine — combined with broader ergonomic controls and a culture of early reporting — is one of the most accessible injury prevention tools available to any employer. Here's what the data says, what OSHA expects, and what you can do about it starting tomorrow.

Key Takeaways

• Over 20% of nonfatal injuries in construction result from musculoskeletal disorders, most driven by overexertion and repetitive motion.

• Nearly two-thirds of all MSD injuries in construction are tied to overexertion from lifting, lowering, pushing, pulling, or carrying — the routine physical demands of the job.

• A daily stretch and flex routine helps prepare muscles for work and supports recovery, but works best as part of a broader ergonomics program that includes engineering controls, task rotation, and early reporting.

• OSHA addresses MSD hazards through the General Duty Clause — employers with workers exposed to ergonomic risk factors are expected to take action, even without a specific ergonomics standard.

• The earlier a worker reports discomfort, the easier and less costly it is to address. Building a culture of early reporting is one of the highest-return investments in MSD prevention.

Why MSDs Are a Bigger Problem Than Most Employers Realize

Sprains and strains don't generate the same urgency as a fall from elevation or a struck-by incident. But in terms of total injury burden, lost workdays, and workers' compensation costs, musculoskeletal disorders represent one of the most significant challenges facing construction and industrial employers today.

According to CPWR — The Center for Construction Research and Training — over 20% of nonfatal injuries in construction result from MSDs, with overexertion and repetitive motion as the primary drivers. When you break down what's behind those injuries, the picture is stark: overexertion from lifting and lowering alone accounts for 30% of MSDs among construction workers. Pushing, pulling, holding, carrying, and catching account for another 37%. That's nearly two-thirds of all MSD injuries tied directly to the physical demands workers face every day — demands that are routine, predictable, and in many cases modifiable.

The physical profile of construction and industrial work makes these injuries almost inevitable without deliberate prevention. About 75% of workers in construction production occupations need to kneel, crouch, stoop, or crawl for at least half of their working time. Many trades involve repetitive hand and arm motions, sustained awkward postures, and work in confined or cramped spaces. The body can absorb these demands — but only up to a point, and only if it's being cared for.

MSDs include injuries most employers recognize: back strains, rotator cuff injuries, tendinitis, carpal tunnel syndrome, epicondylitis, and trigger finger, among others. What makes them particularly costly is that they often develop gradually, go unreported until they're serious, and result in extended time away from work or permanent limitations.

What the Research Says About Stretching at Work

Workplace stretch and flex programs have become increasingly common on construction job sites over the past two decades. The core idea is straightforward: cold, tight muscles are more vulnerable to strain, and a structured warm-up routine prepares the body for the physical demands of the shift ahead.

OSHA's ergonomics guidance supports targeted stretching as a work practice control, particularly for jobs with high physical demands on the shoulders, lower back, and hands and wrists. Stretching helps muscles prepare for and recover from a day of work, and a well-designed program addresses the specific muscle groups most stressed by the tasks at hand.

That said, it's important to set realistic expectations. According to OSHA, work practice and administrative controls — including stretching routines — are most appropriate when engineering controls cannot be fully implemented. Engineering controls remain the most desirable solution: better tools, lift assist devices, modified workstations, and job redesign that reduces the physical demand at the source. Stretching is a meaningful complement to those controls. It is not a substitute for them.

The strongest MSD prevention programs combine physical warm-up routines with engineering solutions, task rotation, and a culture that encourages early reporting of symptoms. Employers who treat stretching as the only intervention are leaving significant prevention potential on the table.

What an Effective Stretch and Flex Program Looks Like

For a stretching program to be worth the time invested, it needs structure and consistency. A supervisor or designated crew lead should guide the routine at the start of each shift. The exercises should be targeted to the muscle groups most relevant to the day's work — not a generic routine that's the same regardless of what the crew is actually doing.

Key body areas for construction and industrial workers typically include the lower back and hamstrings (for lifting and bending tasks), shoulders and neck (for overhead and reaching tasks), and forearms, wrists, and hands (for repetitive tool use). The routine should take five to ten minutes, involve slow controlled holds rather than bouncing, and never push workers to the point of pain.

One important note from OSHA: stretching should never be done to the point of causing pain, and workers under treatment for a musculoskeletal disorder should follow the guidance of their medical provider before participating.

What OSHA Expects — and Why Employers Shouldn't Wait

There is no single standalone ergonomics standard for general industry at the federal level. However, OSHA has been clear that MSD hazards are covered under the General Duty Clause. Employers with workers exposed to recognized ergonomic risk factors — including lifting heavy items, bending, reaching overhead, pushing and pulling heavy loads, working in awkward postures, and performing repetitive tasks — are expected to take reasonable steps to address those hazards.

OSHA's ergonomics enforcement guidance also makes clear that early reporting plays a critical role in any compliant MSD prevention approach. Comprehensive injury reporting is foundational to identifying problem jobs, tracking trends, and determining whether prevention efforts are working. Employers who discourage early reporting — or who fail to respond when workers raise concerns — face both compliance risk and the much higher cost of injuries that could have been addressed early.

Frequently Asked Questions

Does OSHA require a stretching program?

No, there is no OSHA regulation that mandates a stretch and flex program. However, OSHA's General Duty Clause requires employers to protect workers from recognized hazards, including ergonomic hazards. A stretching program can be one component of demonstrating that you're taking reasonable steps to reduce MSD risk. Engineering controls and administrative controls together form the foundation of a compliant ergonomics approach.

Is stretching enough to prevent MSD injuries on its own?

No. Stretching is most effective as one component of a broader ergonomics program. Engineering controls — such as lift assists, better-designed tools, and modified workstations — are the most effective way to reduce MSD risk at the source. Task rotation, proper body mechanics training, and early symptom reporting all work together with stretching to provide meaningful protection.

How long should a workplace stretch and flex routine take?

Most effective programs run five to ten minutes at the start of a shift. The key is that the routine is consistent, led by a supervisor or crew lead, and targeted to the specific muscle groups relevant to the day's tasks. Brief stretch breaks during the shift — particularly after extended periods of repetitive or sustained physical activity — can also help reduce fatigue and injury risk.

What should a worker do if they're already experiencing MSD symptoms?

Workers experiencing persistent pain, stiffness, numbness, or weakness should report it to their supervisor as soon as possible — before it escalates into a serious injury. Workers under treatment for a musculoskeletal disorder should follow the advice of their medical provider before participating in any workplace stretching program.

How do I know if my company has an MSD problem worth addressing?

Start by reviewing your OSHA 300 injury and illness log and your workers' compensation claims. Look for patterns — strains, sprains, and soft tissue injuries in specific body parts or specific roles. If those patterns exist, they're telling you something about the physical demands of your work that deserves a closer look.

Conclusion

Musculoskeletal disorders are not an inevitable cost of doing business in construction or industrial environments. They are, in large part, preventable — and the prevention starts with simple, consistent habits paired with smarter work design.

A daily stretch and flex routine is one of the most accessible tools an employer can offer. It signals to workers that their physical health matters. It prepares the body for the demands of the day. And when paired with engineering controls, task rotation, and a culture that encourages early reporting, it becomes part of a prevention program that actually moves the needle.

The best time to build that program is before an injury shows up on your log. If you're not sure where to start, Allied Safety Group can help you assess your current exposures, build a practical ergonomics program, and train your supervisors and crews on the habits that keep people healthy and on the job.
