As my daughter (age 6) progresses in gymnastics I am noticing that she appears much stiffer than the other girls on her preteam. For example when doing skills such as handstand to bridge and kick over she does the skill but just looks so stiff and not natural while doing it. Likewise on bars -she's recently gotten her pullover and is now working on back hip circle and mill circles and appears very stiff and unnatural while doing these skills. Does anyone have any experience with this?
