Group Fitness Instructor

Answer: B - Viscosity is dependent on both time and temperature, which is why it is important for the Group Fitness Instructor to observe how well participants warm-up before participating in vigorous physical activity. An adequate warm-up will reduce viscosity, increase tissue extensibility, and decrease the risk of injury. Proper feedback can motivate and encourage the participant to take the time to properly prepare the body for exercise and not to see it as “wasted exercise time.”
