Lateral raise

A Cable fly or Cable flye is a strength training exercise in which the hand and arm move through an arc while the elbow is kept at a constant angle. Flies are used to work the muscles of the upper body. Because these exercises use the arms as levers at their longest possible length, the amount of weight that can be moved is significantly less than equivalent press exercises for the same muscles (the military press and bench press for the shoulder and chest respectively). Due to this leverage, fly exercises of all types have a large potential to damage the shoulder joint and its associated ligaments and the tendons of the muscles connecting to it. They should be done with caution and their effects first tested while using very light weights; which are gradually incremented after more strength is gained. With that being said fly exercises are superior when it comes to Increasing the width of your chest.

Flies can be performed using any weight that can be held in the hand. The simplest equipment to use is a dumbbell, though the exercise can also be performed using a cable machine. Flies can be performed supine, sitting or standing upright. When using a cable machine, the hands and arms move through the same anatomical plane as the dumbbell version. Using dumbbells for pectoral flies requires the use of stabilizer muscles associated with performing flies, when compared to performing flies with a cable machine.

The chest fly or pectoral fly (abbreviated to pec fly) primarily works the pectoralis major muscles to move the arms horizontally forward. If medially (internally) rotated, it is assisted in this by the anterior (front) head of the deltoideus in transverse flexion. If laterally (externally) rotated, the contribution of the deltoid is lessened and the pec major is strongly emphasized as the transverse adductor.
