Lower back pain is terrible and best avoided. With some careful techniques and correct lifting a lot off back pain can be avoided. I’ve put together a short presentation video on how to better look after your back and some techniques and tips on avoiding lower back strain and damage to spinal discs
Lifting something of the ground using the legs to squat down
Using the knee and elbow to divert load from lower back
Golfers pick up
Lunging
Splits (abducting legs to alter task height)
I have also included a better way of straightening up from a bent over slouched back.
The key feature in all these techniques is to keep the spine in a neutral / stable position and let all the limbs do the awkward work.
