The way I learned to roll was by first learning a power roll. I’ll explain for clock spin. First face the wind. This roll can be done in all kinds of wind, but I found it easiest to learn it in no wind. So indoors is good. Just make sure you have a high ceiling and no breakables around. It can get a little out of control. Next you need to toss the disc on a very steep angle to your left side. Then curl your left hand towards your forearm and wait with your hand down low, by your hip. As the disc comes down hit it at seven o’clock or so (this is important) with the palm of your hand. Stick your right arm straight up in the air and it will almost track itself. You might have to move your right arm forward a little bit to get it to track, but you will get the idea quick. You will need to hit it a little hard so that the direction of the disc will change from falling to travelling up your chest. As you get good at the power roll you will find that an open chest roll with no uphill travel will become easier. And if you give the open chest roll a little push with a curled wrist it will help greatly in making the disc track across your chest, because you’re giving it a direction instead of letting it roll as it will.
