One of the most common mistakes on cable fly is thinking that you have to keep your elbow perfectly straight or with the same amount of elbow bend throughout the entire range of motion.
However, in my opinion, the best way to do Cable flys is by being dynamic with your elbow joint and allowing the elbow to bend as you bring your arms far apart and straighten as you bring your arms together.
You should find the movement more stable doing it this way.

If you want to grow a "thicker" back, ideally you want to develop the mid-back musculature (basically your traps and rhomboids).
And one of the best ways to do so is with a wide grip row where you can actually squeeze your shoulder blades together.

Normally, if I'm at the gym, I try to avoid doing an overhead dumbbell tricep extension at all costs just because of the uneven resistance profile and lack of stability.
If you're forced to do this exercise, one way to make it better is by using your off-hand to brace and lean so that your elbow is pointed directly to the sky. This way, we're able to get our center of mass going through our body, so we have more balance and there'll be less unnecessary pressure on our elbow joint.

One of the most common signs you're egolifting on bench press is if your glutes are lifting off the bench on the concentric.

- choice is yours.

In my opinion, the best way to do reverse Pec Deck tly tor training the rear Delts is going to be unilaterally facing sideways.
Thia way you're essentially increasing your range of motion in the stretched position, since you're getting your arm across your body, compared to if you're facing against the machine the traditional way.

Doing cable flies on the far-away cables generally feel a little bit awkward due to the limited range of motion when your arms are far apart — thus I usually avoid.
But if you're forced to use the faraway cables, a workaround is to step in front of the cables so that you're able to get a thorough stretch on your chest.
Otherwise, default to using the V shaped dual cable system.

Drag curls are not an exercise I would recommend doing. They do not bias the long head any better, contrary to popular belief.
And while you are getting a better stretch on your biceps at the shoulder joint since you're going to shoulder extension, a better alternative that accomplishes the same thing and is far less awkward to do would be an incline dumbbell curl.

Here's how to make sure this machine press
does not feel awkward or uncomfortable on
your shoulder, and it has to do with how you
position the bench.

Well, the best tips I can give on incline dumbbell bench press that will change the comfort and your ability to take the movement through a full range of motion is tucking your elbows in. This will also help you better bias your upper chest. One of the best tips I can give on incline dumbbell bench is to tuck your elbows.
