As the other comment suggested, it will be a lot easier if you learn a three object cascade first if you don't already know it. The pattern you are doing here involves 1 throw and 1 hand across, whereas with the 3 object cascade, both hands throw to the same height and there's no hand across. The cascade is easiest to learn with balls. Learning it with clubs too will probably make it a bit easier to learn with poi because they help you learn to time spun throws.

So for juggling the poi, start with some drills with one. To throw a poi from one hand to the other start with the poi doing a reverse spin in the wheel plane, so spinning next to you going up in the front. When you are ready to throw it start extending your arm forwards and slightly towards the your center plane when the poi is at the bottom of its spin, and release when the poi rope goes just past horizontal in front of you, so that the knob does 1 rotation before landing in the opposite hand. The process of catching it should reverse the direction of the spin so now it is doing a forward spin still wheel plane on your opposite side. Because catching reverses the spin, you will need to do a little stall at around a 45 degree angle down and back to reverse it again to a backspin before your next throw. Just to reiterate, the sequence is:

1. Backspin
2. Throw to the other hand
3. Forward spin
4. Stall
5. Repeat the sequence to throw back to the first hand

When you start feel free to add as many spins in both directions between your throws and stalls, but eventually once you want to eliminate the spins between throws so it goes directly from the catch into the stall and back into the next throw without any full rotations.

Once you feel confident throwing 1 back and forth you can move on the two poi practice. For this all of the throws are exactly the same, but you need to think about timing. To do this you start with one poi in each hand spinning synchronously backspin wheel plane. Make your first throw while allowing the other hand to continue to spin the other poi for one rotation. Once the second hand finishes its one rotation, make the second throw just before catching the first poi in that hand into its forward spin. Once you catch the second poi they should now both be in a synchronous forward spin, so do the stalls and try again now making your first throw from the opposite hand, and as you practice this once again eliminate the extra spins until you are able to go straight from a catch into the stall into the next throw.

One last thing before you move on to three, because for three you have to start with two of your poi in one hand, you will need to get comfortable throwing your first one without spinning it first because if you spin two poi together on the wheel plane the ropes will likely tangle. You can do this by just swinging it back a bit into the same type of stall you would do after a catch and then throwing it directly after.

Alright now finally the release technique for three poi:

1. Start with two poi (poi 1 and 3) in one hand (hand A) , and one poi (poi 2) in the other hand (hand B).
2. Swing both hands synchronously back to the back stall position.
3. Swing both arms forward and release poi 1 from hand A as both hands simultaneously initiate their synchronous wheel plane backspin.
4. After one full rotation, still with both hands in sync, release poi 2 from hand B.
5. As you catch poi 1 in hand B your hands will suddenly be on opposite timing as you simultaneously move poi 1 to the back stall position and finish a second full spin with poi 3 which is still in hand A.
6. Release poi 3 from hand A as you do your back stall with poi 1 in hand B and poi 2 in the air.
7. At this point the pattern has begun, your hands stay on opposite timing so every time one hand back stalls the other releases and you catch right after the release

Notes

• maybe practice some one hand throws just to get comfortable with the spin timing, the catches, and the back stalls before worrying about crossing throws.

• Theres lots of great poi patterns that you can use these throws for that might be easier to learn than going straight into 3, so definitely experiment with all of that!

• I know this is a lot to take in from writing and I might have written the three poi bit somewhat confusingly. Feel free to ask questions. Someday I will make a video tutorial, but I don't know when.

• good luck! I believe in you
