USA 4 is possible to get this but it's hard compared to Europe 1. During Europe 1 you'll run into 5 trampolines in a row at different levels, just bounce to the end and back and then to the end again and you'll have it.
Tip from the comments: Try using just the middle 3 of the 5 trampolines. They claim that it is even easier than using all 5.
When changing directions try and get your body moving in that direction before you come down on to the trampoline. In other words overshoot the center of the last trampoline just a little and come back to hit the center. This will greatly help to get that little extra distance.
Always aim for the center, this is where the maximum bounce is. There will be a little red dot below your avatar telling you where you will land.
