Every warehouse in Canada has run a lifting course. Most have run several. The poster is still on the wall by the time clause, laminated, showing a figure with a straight back and bent knees. And the back is still the most claimed body part in the country.
That is not an argument against training. It is an argument about what training can and cannot change.
Training changes knowledge. It does not change tissue.
A lifting course transfers information: where to put your feet, when to ask for help, how to break a pallet down rather than reach across it. All of that is worth knowing, and a crew that knows it is better off than a crew that does not.
What the course cannot do is raise the load a lumbar spine tolerates before it complains. That number is a physical property of the person doing the lifting. It responds to progressive loading over weeks, and it responds to nothing else - not to a slide deck, not to a signed attendance sheet, and not to a supervisor reminding the crew at the start of a shift.
So an employer who has only ever bought training has bought the knowledge half and left the capacity half untouched. Then the claim arrives and the response is to book the course again.
The gap nobody measures
Here is the part that makes this expensive rather than merely ineffective: almost nobody knows which of their people are carrying a deficit.
Fewer than half of Canadian organisations track absence at all. Fewer still put a cost against it. An employer in that position cannot tell you whether their crew's lifting capacity went up or down last year, because nobody ever measured it in either direction. The lifting course is not being chosen over measurement; it is being chosen in the absence of measurement, because it is the intervention that is available without one.
What measurement actually looks like
The version of this that works is unglamorous. A clinician brings force measurement hardware to the site and tests each participating worker isometrically - the worker pushes against a fixed pad and nothing moves. There is no lift, no jump and no technique to get wrong, which is why it is safe at any age and any level of conditioning, and why a queue of employees moves through it faster than most employers expect.
The result is a number, benchmarked against age and sex norms. That number does 2 things a course cannot. It identifies who is below the demands of their own job right now, before anything has torn. And it gives you something to retest against in 12 weeks, so the question "did the program work" has an answer instead of an opinion.
Where the training still belongs
None of this retires the toolbox talk. A worker with good capacity and bad technique is still going to reach across a pallet they should have walked around. The 2 interventions answer different questions, and an employer running only one of them is answering half.
The order matters, though. Measure first, because measurement tells you which of your crews need the loading program and which need the 20-minute talk. Run it the other way around and you are buying training for everyone at the same dose, which is the cheapest thing to do and the least likely to move a number.
This piece is our own argument. The figures in it are published Canadian data with the source on every one; the interpretation - that capacity and knowledge are separate purchases and most employers have only made one - is ours, and is not a finding of any of the publishers cited.
If you want to check this yourself
Start with the evidence base, which lists every figure used anywhere on this site with its publisher and a page-level link. Then read Bulletproof Back for what a lumbar loading program actually contains, or injury prevention for how the screening runs on a working site.
