Does anybody have any valid and reliable research that machines don’t use stabilizing musculature?
Hello, Chris!
It is not research needed to prove this. Initially machine had been created to work for people with disabilities. But, if you would like activate your stabilizing musculature when working on machine, use only one arm or one leg. Deep core muscles will tell you big “Thank You”.
