Functional training

Functional training is a classification of exercise which involves training the body for the activities performed in daily life.

Origins
Functional training has its origins in rehabilitation. Physical therapists developed exercises that mimicked what patients did at home or work in order to return to their lives or jobs after an injury or surgery. Thus if a patient's job required repeatedly heavy lifting, rehabilitation would be targeted towards heavy lifting, if the patient were a parent of young children, it would be targeted towards moderate lifting and endurance, and if the patient were a marathon runner, training would be targeted towards re-building endurance.

Functional training involves mainly weight bearing activities targeted at core muscles of the abdomen and lower back. Most fitness facilities have a variety of weight training machines which target and isolate specific muscles. As a result the movements do not necessarily bear any relationship to the movements people make in their regular activities or sports. Functional training attempts to adapt or develop exercises which allow individuals to perform the activities of daily life more easily and without injuries.

Benefits
Functional training may lead to better muscular balance and joint stability, possibly impacting the number of injuries sustained and individual's performance in a sport. The benefits may arise from the use of training that emphasizes the body's natural ability to move in three anatomical planes of motion. In comparison, though machines can often be safer to use, they restrict movements to a single plane of motion, which is an unnatural form of movement for the body and may potentially lead to faulty movement patterns or injury.

Functional training for sports
Many athletes equate strength training with bodybuilding; accordingly, individuals involved in endurance or flexibility-based sports do not strength train for fear of gaining too much bulk and losing flexibility, or mimic the training of bodybuilders without adapting workouts to their specific sports. As a result, training can lack the performance benefits that strength training could provide.

Equipment
Standard resistance training machines are of limited use for functional training – their fixed patterns rarely mimic natural movements, and they focus the effort on a single muscle group, rather than engaging the stabilizers and peripheral muscles.

Preferred options include:
 * Cable machines
 * Dumbbells
 * Medicine balls
 * Kettlebells
 * Physioballs (also called Swiss balls or exercise balls)
 * Resistance tubes
 * Rocker and wobble boards
 * Balance disks
 * Sandbags

Cable machines
Cable machines, also known as pulley machines, are large upright machines, either with a single pulley, or else a pulley attached to both sides. They are extremely useful for functional training as they allow allow an athlete to recruit all major muscle groups while moving in multiple planes. Cable machines also provide a smooth, continuous action which reduces the need for momentum to start repetitions, provide a constant tension on the muscle, peak-contraction is possible at the top of each rep, a safe means of performing negative repetitions, and a variety of attachments that allow great flexibility in the exercises performed and body parts targeted.

Components of a functional exercise program
To be effective a functional exercise program should include a number of different elements:
 * Specific to the sport. Any program must be sport specific, working to develop and maintain sport specific strength.
 * Integrated – It should include a variety of exercises that work on flexibility, core, balance, strength and power.
 * Increases Core Stability – core stability is crucial for any sport or activity. A stable core allows for more efficient transference of power from the lower to upper body, and an increased ability to maintain correct athletic posture over long periods of time.
 * Progressive – Progressive training steadily increases the strength demand from workout to workout. While most people are aware of the need for this in relation to traditional strength training, it is sometimes overlooked in functional training.   For functional training is also means varying speed of movement to make it more sport specific.
 * Periodized – for competitive athletes, their functional training needs to fit into their competitive cycle of competition. In broad terms this means that they will vary their program throughout the year to achieve optimal results, peaking for competitions or races and building in recovery time also.
 * Individualized – An athlete’s program need to be designed for them. The only way to do this is to work with a coach or trainer who specializes in the particular sport and can custom design a program.  A qualified personal trainer can easily include functional training in their clients' exercise programs, whether they are recovering from an injury or preparing for competition.
