The inside outside loop is a combination of the inside and outside loop tricks. You just throw them together. You are just going to alternate inside-outside. You want to be able to control it so that it goes just inside-outside repeatedly. If you're still using your arm a lot to do your loops, it's going to be really hard to control the outside motion on this. So something that you want to focus on is doing this trick using just your finger. This is really going to help you control it from coming outside back in. If you are using your whole hand to do this you will be fighting to get that yo-yo back to where it needs to go rather than when you are just using your finger,
