Human anatomy, unfortunately, does not offer a way to grow your shoulder bones. So the only way to see your broad shoulders to work the muscles that roam your shoulder bones, particularly the muscle that makes up the portion of your deltoid.
“But it’s actually very difficult to isolate that muscle”, says Juan Carlos Santana. “You need to train very hard to emphasize this area of the shoulder: front (anterior), middle, and rear (posterior)’, Santana suggests that you practice the following three shoulder exercises one after another and with equal weight, without resting between exercises.
This will create maximum stress on your shoulder muscles getting great results. Take 7 seconds to play each repetition: 4 seconds down, 1 second pause, and 2 seconds ahead. Do three sets once or twice a week. And rest 2 minutes between each set.
How to Increase the Narrow Shoulders
Lateral raise (works and middle deltoids)
Stand takes a couple of weights, and places them at your sides with your palms facing them. Slowly extend your arms out slowly lifting the dumbbells until your arms are in parallel to the floor. Pause for a second, and returns to the starting position. Make four to six repetitions.
Alternate dumbbell lift (works the rear deltoid and trapezium)
Stand supporting the dumbbells with the palms of your hands facing you and put them up to your thighs. It lifted then the strap for front of you at the height of your armpit, keeping your relaxed wrist. Stay like this for a second and slowly lower the dumbbell. Lift the other dumbbell in the same way as the previous four to six alternating repetitions with each.
Dumbbell press (works the triceps and front deltoid)
Take the dumbbells until your arms are parallel to the upper floor and lower your arms pointing directly toward the sky. In other words your shoulders and elbows should be bent at 90 degrees. With your palms out slowly raise the dumbbells until your arms are completely right. Pause for a minute, and lower them to obtain a position of 90 degrees in each arm. Make four to six repetitions.
