Hi
DD is 8 and does 7 hours a week of gym training, split across an acro group and display team. She's not the best in the group by a long chalk, but enjoys what she does and looks to me to be progressing well. Generally her coaches are lovely and, at DDs level, have an extremely positive approach.
Yesterday afternoon apparently the coaches had the 'tops' sitting on the floor and bent their legs back over their heads (I think). DD is really quite stiff and sore this morning in her upper legs. Is that to be expected as she progresses and they try to extend her flexibility? Any good ways of easing the soreness? She is generally very bendy - kind of child who is to be found taking a nap on the sofa with one leg behind her ear 
Thanks for any advice!
