Push-up i slynge er ganske likt som vanlig push-up, men du får aktivert støttemuskulaturen mye mer.
I denne videoen viser Marius fra Muskelklinikken hvordan han utfører øvelsen korrekt. Han viser deg også en vanlig feil og en mer utfordrende metode med fitnessball.
Slyngetrening har blitt en av favorittene til treningsterapeuter.
Med en slynge får du trent hele kroppen med din egen kroppsvekt. Ustabiliteten gjør at du aktiverer kjernemuskulatur og støttemuskler.
Slyngetrening gjør deg både sterk og utholdende, samt holder kroppen din frisk.

While the push-up primarily targets the muscles of the chest, arms, and shoulders, support required from other muscles results in a wider range of muscles integrated into the exercise.
The rectus abdominis and transversus abdominis contract continually while performing push-ups to hold the body off the floor and keep the legs and torso aligned. The rectus abdominis spans the front of the abdomen and is the most prominent of the abdominal muscles. The transversus abdominis lies deep within the abdomen, wrapping around the entire abdominal area. Both muscles compress the abdomen, and the rectus abdominis also flexes the spine forward, although it does not execute this function when performing push-ups.
The anterior portion of the deltoid muscle is one of the major shoulder-joint horizontal adductors, moving the upper arms toward the chest during the upward phase of a push-up. It also helps control the speed of movement during the downward phase. The deltoid attaches to parts of theclavicle and scapula, just above the shoulder joint on one end, and to the outside of the humerus bone on the other. Along with horizontal adduction, the anterior deltoid assists with flexion and internal rotation of the humerus within the shoulder socket.
The pectoralis major is another main horizontal adductor of the shoulder joint, so it performs the same functions as the anterior deltoid during a push-up. It also contributes to adduction, extension, flexion and internal rotation ranges of motion. The muscle is divided into clavicular and sternal parts. Both parts attach just outside the head of the humerus and run toward the center of the body. The parts then separate, with the clavicular part attaching to the inner two-thirds of the clavicle, and the sternal part to the front of the sternum and the first six ribs.
While the anterior deltoids and pectoralis major muscles work to horizontally adduct the upper arms during the upward phase of a push-up, thetriceps brachii muscles, or triceps for short, are also hard at work extending the elbow joints so the arms can be fully extended. The triceps also control the speed of elbow-joint flexion during the downward phase of the exercise. The closer together the hands are placed during a push-up, the harder the triceps work. The muscle is divided into three heads — the lateral head, long head and medial head. The lateral and medial heads attach to the back of the humerus bone, and the long head attaches just behind the shoulder socket on one end; all three heads combine and attach to the back of the elbow on the other.
