II'm high bar squatting for power lifting. I cannot low bar squat its impossible for me.
I have a good 10 mom belt but in there high bar squat you are suppose to keep your arch in the lower and upper back hard to stay as upright as possible.
It is impossible to arch your upper back and lower back hard and take a big breath in and push your abs into your belt.
If you don't believe me stand up and try it.
So what I'm wondering is..... if I don't arch my lower back and use ï»¿the valsalva maneuver in the high bar squat would ï»¿the intra abdominal pressure still keep my spine safe as it is suppose to do under heavy loads.
