I just think of every exercise as a pull, even if the exercise is traditionally thought of as being a push exercise. This allows me to focus on what the target muscle should be doing to move the weight. I came up with this idea because whenever I performed compound lifts I couldn't really feel them in my target muscle but when I performed isolation exercises I felt them instantly. I thought about why that is and realized that all the isolation exercises I was doing were pull exercises (flyes, lateral raises, leg extensions etc.)and then later realized that all movements are essentially pulling movements. For example, most people think of bench press/dumbbell press as pushing exercises because they are pushing the weight up or pushing the weight away from the body but what you are essentially doing is pulling your arms across your body with your pectoral muscles thus moving the weight that just so happens to be in your hands, just like flyes, with the only difference being with flyes you are mainly moving from the shoulder joint but with dumbbell/bench press you are now moving from the shoulder joint and the elbow joint which allows you to lift heavier weight. Same for squats, mainly thought of as a push exercise because well...you are pushing the weight up or some people use cues like "push the floor away from you." What you are really doing is pulling with your quads to straighten your leg thus moving the weight that is sitting on your shoulders. Just like the leg extension exercise, you pull from the quads to straighten your leg.

I just tell myself, if I'm working chest for example, "light pull from the chest" or "80% pull from the chest." The reason I include the words "light" or "80%" is because I noticed that if I pull with everything I've got all my other muscles start helping to lift the weight and I lose connection with my target muscle, which is not something you want for bodybuilding but would be more suited for powerlifting or lifting maximal weights of any kind. I guess it's the same reasoning sprinters are told to only run 80% - 90% speed because when they are told to run 100% speed they tense up unnecessary muscles and they slow down.
