Strong shoulders are healthy shoulders.
Trick is, we need to make sure that they are strong in every direction. You need to make sure that you can perform movements with a full range of motion, and you need to be strong in those positions. Here are 3 movements that nearly everyone can benefit from performing a few times per week. Either as part of a warmup, or for reps at the end of aworkout or something.
1.- T-Pushup- I love T Pushups. I work with a bunch of high school kids and I have them perform these 4 days per week. Very strictly. A shitty T Pushup is a pointless T Pushup.
2.- Turkish Sit-up- Another thing I love and make kids do frequently. You have to have strong abs to hold those shoulders up. So this exercise kills two birds with one stone. You can do these daily in your warmup with a light weight, or, you can do them at the end of your workout with a heavier weight. Remember that maintaining shoulder position is key.
3.- Half kneeling press- This is a go to for a guy/girl who has a hard time overhead pressing and without excessive extension of his lumbar spine. The person who’s ribs flare up when they go overhead. The half kneeling position is useful to help build the strength maintain rib cage position while going over head. That is good. Same deal with these. You can load them up a little for reps at the end of a workout, or do them light in your warmup. If you have trouble maintaining a good overhead position, do them frequently.
