Which of the following is an essential point to consider for safety in aquatic exercise?

Using appropriate depth and temperature for the exercise is vital for safety in aquatic programs. Water depth affects how exercises are performed and the risk of injury; for example, too shallow water may lead to hard landings, while water that is too deep can be unsafe for certain activities. Additionally, the temperature of the water is crucial; exercising in water that is too cold can lead to muscle stiffness and increased risk of injury, whereas water that is too warm might cause overheating and dehydration. Ensuring that both parameters are appropriate is essential for creating a safe and effective environment for participants.
