Do you want to have impressive chest muscles? If so, there are a number of exercises you can do to target this area. One of these is the pec flye. You do the pec fly on a machine called a pec deck. Pec machines are created for weightlifters and not only enhance the pectoral muscles but also the shoulders, back and arms. The major muscles worked include the pectoral muscles, the lattisimus dorsi, the trapeziodis and the rhomboids, which are located in the shoulders and back.
The pec deck has proven itself useful to weight lifters, and have often given very good results. Pec decks are multifunctional. You can perform not only pec flyes but also reverse pec deck flys. You can even perform one-arm rows.
There are some dangers of using a pec deck, however. The pec deck can lead to injury. This is because the angle between your arms and the pad is not optimal. If you sit on the machine you will have to make a goal post shape with your arms. This means they are out to the side with your elbows at shoulder level, and arms pointing straight up. This puts the shoulder joint at its weakest position. You run the risk of dislocating your shoulder with this exercise.
The chest is one of the strongest muscles in the entire body. It is also the primary muscle targeted by the pec deck. As the muscle contracts, it brings the arms in front of you with your shoulder joint left in this worst possible position. You could injure your shoulder or rotator cuff muscles. There are many other exercises you can perform to work your pecs, so you should avoid the pec deck unless, like the Nautilus pec deck, it is specially designed to avoid this problem.
Think about how your pectoral exercises fit into your general training plan. Part of this involves being aware of the maximum and minimum weight that each user will need in order to perform their exercises over the course of time. A weight stack with a minimum of 5 kg (ten pounds) and a maximum of 90 kg (200 pounds) will suit most weight lifters, but if you plan on doing a lot of heavy lifting, or you are inordinately large, you will need a greater range of weights.
When performing any weight lifting exercises, you will need to be precise about your technique otherwise you risk needless injury. Correct technique is everything when lifting weights. It is how you will get the most benefit and do the least harm to your body. Don’t overdo it when you start your program and use common sense. Like any exercise program, you don’t want to overdo it at first.
Train according to your goals. If you are going for endurance, you will need to do high reps with relatively low weight. If you are going for bulk you have to do heavier weights, but you will do a lower number of reps.
