If your child is wishing to do gymnastics and prefers to practice mainly floor elements then this maybe an option. In Acro, which is short for Acrobatics, children learn to do all the basics of floor but in addition they do balances in partners and groups, catches and holds, and routines for floor. In tumbling, the children do the more dynamic floor exercises and make use of the air track. So if learning to do back flics, round offs and walk overs is of interest then Acro and Tumbling is worth a try.
