They all love a pretty pair of shoulders. Your front deltoid muscles are pretty strong if you have a well-built chest, but you still have to work on your rear deltoids to ensure that, in contrast, the top of your arm does not appear deflated and frail. All your lifts, including your weaker delts, will be affected by this imbalance, so you want to fix it as soon as possible.
A rounded muscle in the form of a triangle at the top of your arm where your shoulder attaches to your arm is the rear deltoid. While the 'shoulder muscle' is often referred to, it should not be mistaken and is not synonymous with your trapezoids or your upper back. Three muscle fiber bands are made up of the delts,Three main shoulder components are included: anterior, posterior and medial. When viewed from the side, the anterior is on the front of your arm and goes into the chest, the medial is the tiny piece of muscle almost in the center of your shoulder, and the posterior deltoids are on the back of your arm.
If you want to flex your shoulders, the anterior deltoids support your chest muscles, and when you need to move the humerus, they also help both your pectorals and your lateral muscles. When you need to stretch the shoulders, your posterior delts support your lateral musclesVia electromyography, medicine has found that at least seven muscle fibers are composed of the delts, each regulated separately by the nervous system.
1* Rear Delt Fly
The rear delt fly is the opposite of a chest fly, practically speaking. It can be done with dumbbells or with a fixed motion system. Set up a bench at an inclined angle when using free weights, and face the headrest for support with your chest against it. Start with the weights in front of you, so you slowly carry them back in a horizontal motion.
2* Rear Delt Cable Fly
Using cables would give you a more natural range of movement similar to the previous exercise and will also allow you to lift heavier weight than you can with dumbbells without taking balance out of the equation.
3* Rear Delt Raise
These can be carried out from a standing or sitting position. You need to start with your chest facing the floor as much as possible, either way. The dumbbells in each hand should be extended in line with the center of your chest, along with your sides. Lift your arms up, hold them straightuntil they are just past your back, then lower, as in a rear fly.
4* Rear Delt Row
It is possible to do this exercise in many ways. The general goal is to start by stretching your arms straight ahead of you and pulling back a weight in a rowing motion. You can perform the exercise using dumbbells while straddling an inclined bench if you do not have access to cables or fixed motion machines.
