- Water aerobics is the process of doing cardio and strength training exercises under water. This type of exercise is good for people with joint problems and stiffness because it increases flexibility.
- Water provides natural resistance as the body moves through it. Having resistance during exercise is shown to improve flexibility according to a study published by the "Medicine & Science in Sports & Exercise" journal of the American College of Sports Medicine. Resistance lengthens the muscles and is shown in a study by Len Kravitz, Ph.D and J.J. Mayo, Ph.D. to be more effective than other forms of exercise in creating more flexibility.
- The buoyancy of water aids in the increase of flexibility by making it easier for people to preform resistance exercises. Waist-deep water decreases the pressure of 50 percent of your body weight while chest-deep water supports 90 percent of body weight. This quality also helps stretch the muscles and connective tissue by relieving pressure, making the body more flexible.
