Use the armrests:
GlueBall is correct, it is a pilot problem and it's compounded by a reluctance to use the armrests. Apart from comfort armrests are there to purposely restrict the heavy handed as they (armrests) ensure that the arm and wrist muscles are used rather than the shoulder muscles. This helps to ease into the correct rotation rate as opposed to hauling and jerking. The USAF C5 A policy is to use armrests ( although I am not one hundred percent sure if they are compulsory or not). They must know something that civilian aviation doesn't as they don't seem to have a tail strike problem.
