(Post 85) Common Mistake # 7
We all know lifting with our back instead of lifting with our legs hurts the lower back, but do you know why?
Here are some of the reasons:
1. Bending the lower back creates massive compressive forces to the spinal discs from the contraction of the back muscles.
2. Flexing the lower back forwards pushes the nucleus of the spinal discs backwards into the spinal cord and nerve roots.
3. Whatever you are lifting, multiply the load by 15, that is the amount of pressure that will compress your spinal discs, and that is not taking in consideration your upper body weight which adds to the compression.
I will be in Spain...I will be back soon!!!
