RE: anyone have ideas for a
Maybe do a warm-up that includes some squats (to warm up the glute area) and some kickboxing punch twists (without the punch) to hit the obliques. Then go to the floor for concentrated ab and glute work. Dependiing on how advanced you want it to be, here are some suggestions:
Abs: dead bugs hit the transverse abs. Reverse curls and variations hit lower rectus. Bicycles are one of the best exercises for abs. Planks will hit the whole core and get the glutes a bit as well for stabilization (front planks and side planks).
For glutes: glutes raises done while lying on back (with both feet on floor and with one leg held up in air). Those "donkey kick" moves work well(on all fours, with bent legs, bring the heel up and down) and you can do variations like crossing the knee over in the down move or using a straight leg.
Could you incorporate some play balls? They could be held between the knees for reverse curls, squeezed between the calf and hamstring on the "donkey" moves, and used in different ways to add some intensity.
Finding a nice flow to the moves would be nice, like going from lying abs to the glute raises, then from a plank to the donkey move.
For music, I always prefer music with a driving beat that keeps me motivated and pushes me to go beyond what I would do without music.
Oh, I just saw it is only 1/2 hour! LOL!
