I had to do this workout several times (and rewound a lot) before I got the choreography down, so don't feel bad.
Here's another description of how to do a ricochet:
Okay, so there you are, stepping away with Step Blast, and the ricochet is coming up...what to do? Don't panic. You are facing your step and you're going to be ricocheting to your right. To ricochet to your right, your left foot goes up on your step, and your body turns to the right as you swing your right foot up behind you and over your step to the front side of it. You touch your right foot down on the front side of your step, then immediately "ricochet" (or rebound) your right foot back up and over the step to the back side where you started. To ricochet to your left, your right foot goes up on the step while your body turns to the left and your left foot swings up behind you and over the step, taps down on the front side of the step, then immediately rebounds back up and back over the step.
The sequence is v-step, hitch-kick, charleston kick, and then ricochet, correct? So, when you're leading with your left foot, the Charleston kick is: step up with the left foot, kick with the right, step down with the right foot, and step back with the left...then you lead into the ricochet by immediately pulling your left foot back up and onto the step, turn to the right, and swing that right leg back and over, then reverse it back and over again.
I hope these two descriptions can help you get the ricochet mastered. Just go through these steps slowly several times on both sides before your next attempt at Step Blast. I would even practice them with the Charleston kick. Start off slowly, then work up the speed, then when you're getting comfortable with it, throw in Step Blast and go for it!
You CAN do it! And Step Blast is so much fun once you get the footwork down!
