Answer: A - The three major ways that the body works to balance itself on an unstable support surface are called ankle strategies, hip strategies and a widening of the base of support by stepping out. Overly soft floors can create balance challenges by requiring constant corrections and adjustments from ankle and hip muscles. Unless these corrections are produced in a timely matter, this creates a situation where the exerciser is pushing up against the end range of his or her ligaments and must rely on the ligament to provide stability, instead of the muscle groups contracting and co-contracting to do so.
