[...] For men especially, constant practice with a lady providing feedback on your lead is needed. And at some point getting that practice with your pro is needed, though an amateur partner can go a long way.
For
follows, plenty of practice with someone whose leads are confident and clear is important and could go a long way. It's the only possible way for most follows to learn "move yourself as soon as you feel the lead" and to "commit to what you started to do". It can be difficult to find an amateur partner to dance with whose frame, knowledge of steps and ability to time leads is good enough to be helpful in that regard.
Because
that partner is not any ole' Am lead.
And I'm also learning more and more that one of the problems with group lessons and/or social dancing is that at least
I want to be "cooperative". Since almost by definition the leads in group class do not really know how to lead the new step right, the lead can be tentative and even
initially contradictory. Similar contradictory things happen on the social floor. And sadly, this doesn't just make it hard to move as soon as I feel "the lead" (because I know the lead I feel is often not the "final" or "real" lead.) It also makes it difficulty for me to "commit" to what I am doing in response to the lead. And sadly, if you "cooperate" with a changeable or unclear lead
which then changes, and move involves any sort of change in direction-- pivot, turn etc. -- getting prepped to move or turn one way and then having the lead change to the other stresses knees. It doesn't immediately blow them out, but legs are worn out in a bad way at the end of the evening.
So for a follow, dancing with an amateur who is
not a quite good lead can actually almost be "un-practice". You are rewarded for being tentative, not moving as soon as you should, and end up doing some moves that stress your legs and to some extent back in unproductive ways.
So practicing with a
good lead would helpful, but it's generally hard to find one who wants to devote and hour or two a week with you. The Am leads who've trained enough to be
good clear leads generally want to dance with a follow who is rather better than I am!!
