Re: âWhen I try to add more momentum, I find it hard to rotate hips just at the right time.â
-----------Whenever you change something substantial in your delivery, whether itâs a mechanical change or a timing/sequencing change, you should expect that it will be difficult for a while and you shyould expect to feel awkward and/or uncomfortable during the early stages.
There is simply no way around this basic fact of life: If you develop a set of mechanics repetitively over a long period of timeâŚwhether they are efficient or inefficient mechanics, you will be âcomfortableâ as long as you continue to perform them in the same way you are accustomed to doing.
People have different estimates; however, the rule-of-thumb that makes most sense to me is: If you are trying to make a substantive change in some aspect of your mechanics, it may require ~1000 repetitions of the new motion to make the change a permanent part of what you do.
Especially in the early stages of making a change to your mechanics, you must consciously instruct yourself to do the new thing on every repetition, because it will feel awkward and uncomfortable. In early stages, as soon as you lose concentration on the change you are trying to make, you will tend to lapse back into your old, comfortable habitsâwhatever they are.
