Walkovers put a lot on pressure on the back and should not be practiced at home on a regular basis. Anything with impact (roundoff, BHS) should be avoided as well.
I agree with this!!
My kiddo could not practice RO-BHS at home until recently(it was just determined that she will do L4 & L6 this year, about the same time she could do these at home)& its is VERY limited, most times they say to cartwheel or walk her tumbling passes when practicing routines at home(or add the tumbling pass x1 and x4-9x run it with no tumbling pass)
Her coach got SO upset with her for doing a back-tuck at a sleepover last week(like REALLY REALLY upset-and her coaches never get upset with her).
During the conversation with her coach, I found out she is not supposed to be doing RO-multiple BHS at home either(she has been doing this for months with up to 4BHS, I didn't know better).
Seriously, your daughter could get hurt, even become paralyzed doing some of these skills at home. I know my kids coaches tend to be super extra cautious with my kid(like beyond whats normal), however the same rules need to apply to ALL kids for safety sake!! It's not good for them long term, it puts them at risk for serious injuries short term!!
That said, there is nothing wrong with buying a panel mat for use at home! We have 2, one is a custom from a mat company, the other is a tumble trak. They're great for practicing jumps and routines and stretching.
P.S. when my kid was still trying to tumble at home, I talked to her coaches about increasing her hours. I highly recommend that!!
