Answer: C - The American College of Sports Medicine’s 2011 “Guidance for Prescribing Exercise” states that muscle tissue responds to stretch best when warm. This can be achieved by performing a short bout of light aerobic activity before initiating flexibility exercises or by stretching in the tub. A stretching regiment does not have to be obsessive to be effective; two to three days of regular exercise is sufficient. Any stretch designed to improve ROM should be held between 10-30 seconds, then repeated, leading up to a total of 60 seconds per stretch. And despite popular misconception, static, dynamic, ballistic and PNF stretches are all effective means of addressing flexibility.
