Just variation on using a weight plate, kettlebell, or the weighted clubs.  Keeps shoulder joint mobile and you need to have control over a lot of the musculature of the shoulder.

1) Trap 3 raise or even Lu raises
2) A, Y, and T exercise
3) Push up Plus
4) Shoulder CARS

Great, you don't recommend.  Duly noted.  You have never heard of winging scapula yet you throw exercises at him. 

Not all 'lettered' exercises are to be thrown at this.

External and Internal rotators are NOT direct issues of winging scapula.  Your 'standing front arm raise' is called scaption and it does NOT handle "any" pain.  It will address serratus, lower trap, and supraspinatus if done properly.  Put people against a wall or have them do it seated with a back rest and there is a dramatic difference in the weight being used (reveals how much swinging and cheating is done).

No, it’s not a good video. None of his videos are.

He’s a vindictive, jealous, snarky little asshole.

He baited Big Mike VanWyck into a confrontation and then played the battered victim.

He also tried to get Greg Doucette to hit him and screamed at Greg’s brother off camera once he confirmed cameras were off.

Jeff the little dwarf loves to act sweet and genuine on camera, but then is a conniving and confrontational little asshole off camera.

Jeff loves to post snarky little comments and then suddenly delete them as well.

Him and his girlfriend make quite the couple I must say. Jeff the effeminate garden gnome and his repulsive whack job girlfriend Fat Lard Steph Big Mama Buttermore with her Botox Gone Wrong melting and disfigured ghoul face.
