This is fascinating.
The greatest strain on the low back is…
sitting down and lifting weights.
And what do most people do in the gym?
Sit on a machine and lift weights!
This is the complete chart below.
This chart is from a Gray Cook lecture on the Functional Movement Screen. Apologies, I don’t have the source.
The Surprising Results
Sometime ago, a research study implanted little sensors into the spinal discs of the subjects. The actual pressure inside the spinal joints was measured.
Look at the chart and see that:
- Sitting down with a load was much worse than bending over with a load! And the bending over was even done with improper mechanics.
- Flexing the spine is worse than extending the spine.
Does anything here surprise you?
Just another reason to learn to use your kettlebell.
