Question: what is the difference between a dominant and nondominant hand?
Answer: In 1954, Bechtol developed the 10% rule, which claims that the dominant hand possesses a 5 to 10% greater grip strength than the non-dominant hand. Although Bechtol discovered that the dominant hand could be up to as much as 30% stronger than the non-dominant hand, the most common difference was 5 to 10%.
