at the same time + English -taneous
1. existing or occurring at the same time : exactly coincident
Nothing says that simultaneous movements are identical movements (or did I come in late and that's already been said?).
I even use the movement of holding the inside foot outside edge for an instant (no longer) while I tip the outside foot to its outside edge while I'm on my Harb Carvers®. In these pics
, Jay appears to have the inside foot tipped more than the outside foot in shots 4 & 5. I'll never be as good as Jay, but the Carvers are fun and very instructive for the off season. They are unforgiving and show no mercy...skate right or you'll know it.
I'm not sure it's possible to tip the inside foot more than the outside when both are loaded. The muscles to invert (tip to the outside) are weaker than the muscles to evert (tip to the inside).
