- As with all physical fitness programs, people should have the approval of a healthcare professional before starting. This is in the person's own best interest because not every program is appropriate nor safe for a given individual.
- The impact of jumping up and down is reduced by water support. So there is much less stress on joints like the ankles and feet. These same movements are also much easier on the back, because water support lessens the impact.
- People with arthritis, a bad back, or other problems find it easier to exercise in water than on land. But not all movements are safe while exercising in water. It is important to use common sense. A healthcare professional can advise whether leg lifts and body twisting should be done by someone with back problems.
- Water gives even the heaviest person support, if the water covers at least 75 percent of the body.
- For pregnant women, a new target heart rate must be evaluated by the healthcare professional. The speed of exercises may have to be reduced. The heart rate may have to be kept lower than usual to protect the baby. But movements need not to be restricted, as long as the woman feels comfortable, and the professional approves.
- Water and air temperature and humidity play an important part in water aerobics. Water or air temperatures above 85 degrees F put a stress on the cardiovascular system. A slower pace is then recommended. Lower water and air temperatures allow for faster movements for a longer period of time. High humidity stresses the entire body, and raises body temperature and heart rate.
- Using exercise equipment in water can be a great aid to physical fitness. But how the body reacts to movements with these tools should be understood before they are used. A safe water aerobics program includes instruction in water exercise skills.
