First 32 count warm-up (64 for both sides):
The Grapevine-Ham curl combo gets more interesting with an arm
pattern that is as follows:
Press both arms down (2 counts), press in front (2 counts),
press up (2 counts), press front (2 counts).
This coordinates really well, but may take a bit of time to
teach. I suggest simply doing the arm movements with stationary
ham curls before adding the lateral grapevine movement.
Breaking all this down and teaching it normally takes 7-8
minutes, so it's a great warm-up that you can add onto as the
class progresses.
Second 32 count warm-up (64 for both sides):
This seemingly simple count can really get the group motivated. I modify/intensify by adding a YELL from the group at counts 4,8,12,and 16. This coincides with a knee up and we can always visualize fighting someone off and yealling "HA!!" They really get riled up when I suggest this.
Also, the hamstring curls and knees accross can be made high impact with hops (always hitting the heels on the curls, but staying on the toes for the knees across) and HUGE ARMS!!
The Ham curl arms go from above the head to a huge bicep curl swinging back behind you, and the Knee start witht he arms both up and out as far as you can reach, then swinging the opposite elbow down to meet the knee! When the class gets going with the arms, it looks as though they're EXPLODING with ENERGY!!
I presume you can all break these down yourself. If not, go ahead and email me.
Also, if you have any ADVANCED or MODIFIED DANCE moves; my expert students (half my class) are always aching for complicated new stuff!
Good Luck, and SCREEEEEAM WHEN YOU'RE HAVING FUN!!!
