when crocop first came out, someone (quadros) said that he didn't have any training partners, that he just "kicked air." my question is, do any of you have difficulty with just kicking air? as in, working your teep or teh (spelling?) and not hitting bags/pads... for me, master usually has me working with air, he says it helps to work balance and technique. but then when it's time to work the pads, or when it's time to spar, i'm just not used to the change in weight, and it totally throws me off. what do you guys think? anyone else have trouble with this?
