There is no one-size-fits-all answer to this question, as the fastest way to build shoulder muscles will vary depending on your weight and muscle mass, as well as your training regimen. However, some tips that may help include performing heavy compound exercises using a moderate amount of resistance, lifting weights slowly and deliberately (without bouncing), and focusing on proper form when doing these exercises. There are a variety of exercises that can help you develop strong shoulders, but the two most common types are the military press and shoulder raise.
The military press is a classic compound exercise that works your entire chest, back, and arms. To do it properly, start by lying facedown on the floor with your palms flat on the ground next to your hips. Lift your upper body off the ground using just your muscles (notyour joints), so that you’re in line with straight arms and shoulder blades retracted towards each other. Drive through heels into the ground as you lift weights offthe floor toward shoulder height explosively 3 times without pause. Lower weights to starting position before repeating.
Shoulder raises work both deltoids simultaneously by raising one arm above head while keeping otherArm at side or behindback(depending uponarm length). Hold weight in left handwith palm facing down; extend right arm horizontally so fingers point forward, then slowly lower weight until forearm is parallel tofloorwhile maintaining 90-degree angle between elbowand wrist.(If performingright handedshoulder Raise remember to rotate hand so thumb points up when lowering)alternating sides 2-3xbefore moving onto new target muscle group1xper day
