I would recommend watching lots of routines and you'll pick up on poses that you like. Try going to youtube and searching for gymnastics from the 1980s and early 90s - there's some really original dance moves from those time periods.
Hey girl! So I choreograph for all of my gymnasts and at times I even struggle once in a while trying to figure out new stuff!! Ask yourself what you are good at- flexibility or strength..both??? Are you a dancerâ€¦or not really?? Whatever you are good at, use it!! If you are strong do poses that show off your musclesâ€¦.are you flexibleâ€¦..do things that show of your flexibility (judges love that stuff). Go to u-tube and check out stuff theirâ€¦..turn the radio up and just let your body move to the musicâ€¦.maybe something will just come about- and then use it! Always remember a person can have the smallest/simplest dance poseâ€¦.but if you throw that chin up and chest outâ€¦.itâ€™s going to look good! Good Luck!!
