The difference between calisthenics, isometrics and Pilates is in the method each uses to improve physical well being. Calisthenics focuses on movement, isometrics concentrates on improving strength through static or stationary positioning, and Pilates exercises the mind to control breathing and muscles, specifically those in the spine. While the exercises can be performed independently, all three are sometimes included in a comprehensive exercise program.
Calisthenics are what many people did for exercise in the 1950s to keep in shape. They were very popular with the military and on emerging television exercise shows. They increase body strength through a variety of simple, repetitive movements that rely on a person’s body weight for resistance. Some people use weights to enhance the results of calisthenics. The most popular calisthenics include jumping jacks, sit-ups, squats, push-ups and crunches.
Isometrics do not involve the rapid motion of calisthenics. They are designed to increase strength through positioning certain joints and muscles in static or stationary positions that provide resistance. Isometric exercise normally uses an immovable object, such as a wall, for resistance. The muscles contract and joints are strengthened through static resistance supplied by the wall. Another example would be to hold a weight straight out to the side of your body with your arm extended; strength is developed by holding the weight still, not through lifting. Each isometric movement is held for six to eight seconds and involves five to ten repetitions.
Although isometrics date back thousands of years and have roots in yoga and Asian martial arts, they were first embraced by the public much later. Early on, modern bodybuilders hailed isometrics as the key to building muscle mass. Some controversy emerged after it was later discovered that true isometrics were not effective body-mass building exercises; putting limbs in opposition to each other or to a stationary object builds strength, but not mass. The controversy grew even stronger when it was discovered that, in many cases, much of the impressive strength in the competitors’ bodies was the result of anabolic steroid use.
Of the three exercise models, Pilates is the most recent trend in exercise programs. It was created in Germany by Joseph Pilates in the early part of the 20th century. He dubbed the method Contrology and believed that physical fitness could be attained through strengthening the deep torso, or core, muscles. Pilates taught that the mind could control breathing and the spinal muscles. His method professes the entire body benefits from controlling breathing and improving spinal alignment.
Before starting any exercise program, a physician should be consulted. Some types of exercise may be too strenuous or inappropriate for those with physical limitations or chronic ailments. A doctor may also recommend certain exercises over others based on a person’s age and general health.
