user9269: I use normally: loopOut('cycle') expression to loop a movement. But sometimes I want to loop an animation like this: 

1-3 frames -> rotation 30deg
3x loop a full rotation 
after looping -> add 10 other frames and 
make rotation 120deg

How is it possible to loop between this actions and not using copy+paste?  
Here is a link to my work 
I loop the arms motion, but as you see in the first frames the left arm has to wait until the right arm does the first half of the motion. If I add a half motion to the left arm I can't loop it. I would have to avoid copy+paste because I want to loop it 40 times. At the end of my animation I also need a different motion with the right or left because the swimmer has to touch the wall with two hands. I hope, I was clear. 

user8064: Using time remapping could be a solution. You animate one full circle of the animation and precompose this. Then you time remap that layer and use loopOut('cycle').
