Keep Your Arms Straight
Make sure that your arms are straight. There's no need to bend your arms until the actual moment when you begin to do the dynamic movement. And, the longer you keep them bent, the faster they will become tired. Additionally, keep in mind that though you will be utilizing some arm strength to pull yourself up the wall, when doing a dyno your arms should actually be more focused on guiding the force and direction of your movement.
Keep Your Hips Close to the Wall
Keep your hips close to the wall by thrusting your pelvis toward the wall and holding it there. When doing a dynamic movement, if your butt is sticking out away from the wall you are going to have a much harder time jumping upwards because your butt will be pulling you back and off the wall.
Keep Your Weight Over Your Feet
Your weight should be mostly on your feet, and you should use your legs to power yourself up the wall. Drive the force of your dynamic movement by pushing hard with your legs when you are ready to make the dynamic movement. Some people will pump before they make a dynamic movement, but this isn't necessarily helpful and will likely just tire you out.
Sticking the Hold
When learning how to make dynamic movements, consider the hold you are aiming for. As you make a dynamic movement, there is a point at which the upward movement of your body stops and you begin to fall out and back (this is sped up if you stick your butt out). Learn shorter dynos first so that you can master "sticking" the hold, which means your hand should be at or slightly above the hold so that as you fall out you can fall onto the hold.
