🤯 Biomechanics is mind-blowing.
An exosuit can relieve an estimated 26 MILLION pounds of cumulative peak force from a warehouse worker’s back each year.
We tend to get caught up thinking about and discussing EMG reductions, percentage offloading, or the biomechanics of a single lift.
But often we’re losing the forest for the trees.
Zoom out.
2,000 lifts/day
× 260 workdays/year
× 50 lbs of peak back force offloaded per lift
= 26,000,000 lbs/year
That’s equivalent in weight to 325 fully loaded semi-trucks that a person's low back doesn’t have to endure each year.
Now try to wrap your head around that cumulative physical relief over 5 years. 10 years. An entire career.
The biomechanics of a single lift matter. But ultimately, we care about what those small reductions add up to—for injury risk, fatigue, physical well-being, and people's ability to go home feeling better after years of physically demanding work.
