I've always struggled BIG TIME with incline press and shoulder press, particularly when using dumbbells...it's really starting to make me angry. I simply cannot push myself on it, relatively "light" weight, I can smash out a quick 5 reps and then once it starts to become heavy, I simply can't overcome that mental block where your mind says "no, no more of that" and refuses to allow you to push out the next rep.
Anyone got any tips for how I can overcome this? It's seriously only with those 2 exercises. Just as I get to the most effective point and it's doing something, it's all over. Like my arms aren't in my control any more.
