Techniques Water aerobic workouts usually combine a variety of techniques from land aerobics, including walking or running backward and forward, jumping jacks, mimicking cross-country skiing, along with various arm movements. The workout also may incorporate equipment such as flotation devices.[1] Benefits In addition to the standard benefits of any exercise, the use of water in water aerobics supports the body and reduces the risk of muscle or joint injury. The mitigation of gravity by flotation places less stress on the joints when stretching, and can allow a greater range of motion. The mitigation of gravity makes water aerobics safe for any individual able to keep their head out of water, including the elderly.[2] Exercise in water can also prevent overheating through continuous cooling of the body. Most classes last for 45-55 minutes.[1]
