It's not difficult to get the dumbbell to the shoulder. I could clean much more weight than I can press. But when it's up there, balance is the main challenge, and then pressing (actually jerking) straight up. If you lose it in any direction, you'll miss the lift. And when you can't grip it well, it's very hard to position and press, particularly if you're someone like me who has shitty shoulder mobility. Wrist positioning is also difficult, making sure that everything's well aligned for the jerk. And then when you take your dip, it's easy to lose it. I could go on and on about how much it sucks, lol.
