A 2020 study out of Japan found that regular calisthenics can help people preserve skeletal muscle mass. The study looked at people with type 2 diabetes. People with diabetes are at a higher risk of losing skeletal muscle mass, which can cause mobility issues later. The Japanese study had the participants do radio calisthenics (which are popular in Japan). These are simple exercises that people can perform regardless of age. These exercises encouraged people to move their muscles and joints, following the rhythm of the radio. The group that did calisthenics lost almost 50% less skeletal muscle mass as the group that didn’t. Anything you can do on solid ground, you can do in the pool. A 2020 study found that aquatic calisthenics can help improve fitness and reduce body fat. Calisthenics can challenge your strength and focus. They can also mimic moves that you do in everyday life and will need to be able to do over your lifespan. For example, squats are a form of calisthenics. This exercise also helps you maintain your ability to squat down safely in a chair and stand up again.
