BACK PAIN - so common and a lot of fear behaviour.
But it is not all doom and gloom - most back pain recovers. A big part of recovery is rehab and strength. Here is Brian demonstrating correct deadlift technique. Notice the spine stays in a neutral position, and he hinges at the hips. By doing this, he is loading his glutes and hamstrings to protect the lower back. This is what is often meant by lifting with your legs.
Deadlifts are a very important exercise in correct lifting technique - instead of the bar, imagine a washing basket, grandchild, schoolbag or bit of furniture.
Most people with back pain will be told not to lift. That is correct - ONLY in the early stages. The back is strong, discs do not slip, the spine does not go out of alignment and lifting is vital for everyday living!
So don't fear it - train it! We need to bend and lift - if you rehab your injury properly, you will be able to get back to the things that you love.
