With more than 13,000 affiliate centers (boxes) around the world, CrossFit is the exercise fitness program of choice for individuals of all ages. More than half of the centers are in the United States. Founder Greg Glassman, over several decades, developed a fitness program to improve fitness and health. (Source: http://CrossFit.com)
CrossFit workouts incorporate elements from high-intensity interval training, Olympic weightlifting, plyometrics, powerlifting, gymnastics, girevoy sport (kettlebells) calisthenics, Strongman, and other exercises. (Source: Wikipedia.com)
- High-intensity interval training – a cardiovascular exercise strategy alternating short periods of intense anaerobic exercise. The exercise sessions generally consist of a warm up period, then several repetitions of high-intensity exercise separated by medium intensity exercise for recovery, then a cool down period. These intense workouts typically last under 30 minutes, with times varying based on participants’ current fitness level. It is used by athletes in non-endurance sports to promote strength, speed, and power and by body builders to build muscle mass. Anaerobic exercise examples: walking, long-slow runs, running, cycling, and rowing.
- Olympic-style weigh lifting – Athlete attempts to lift a maximum weight on a barbell. Examples: Snatch and Clean and Jerk.
- Plyometrics – “jump training” or “plyos” are exercises in which muscles exert maximum force in short intervals of time, with the goal of increasing power (speed strength). This training focuses on learning to move from a muscle extention to a contraction in a rapid or “explosive” manner, such as, in specialized repeated jumping.
- Powerlifting – a strength sport that uses the squat, bench press, and deadlift.
- Gymnastics – sport involving the performance of exercises requiring balance, strength, flexibility, agility, endurance, and control. The movements involved in gymnastics contribute to the development of the arms, legs, shoulders, chest, and abdominal muscle groups.
- Calisthenics – exercises consisting of a variety of gross motor movements – running, standing, grasping, pushing, etc., often performed rhythmically and generally without equipment or apparatus. Increase body strength, body fitness and flexibility, through movement such as pulling or pushing oneself up, bending, jumping or swinging using only one’s body weight for resistence. Usually conducted in concert with stretches. When performed vigorously and with variety, calisthenics can provide the benefits of muscular and aerobic conditioning, in addition to improving psychomotor skills such as balance, agility and coordination.
