The Bottom Line: Squat vs Stoop Lifting: Which is Safer?

Written by: humantech on February 1st, 2017

Humantech ergonomist Blake McGowan shares the ground-breaking results from a 2016 study that measured the spinal loads during both squat and stoop lifting in this month’s bottom line video.

The German researchers found:

  1. Lifting an object from the ground results in significant spinal loading regardless if it was a squat or stoop lift.
  2. The spinal forces were the same for both. In fact, the forces were 4 percent greater for a squat lift.
