My DD just moved to L5 in January, and the coaches are having her switch legs on the cartwheel on beam (she used to go left foot forward), which she was told is necessary for L5 and beyond. I'm not questioning them - I assume they know what's best, but I am kind of curious as to what difference it makes. Does anyone know what's different about which leg you lead with? Is it just about how it connects from or to other elements, or is there something about the skill itself?
