Do isometric excercises burn calories effectively?

Just wondering if they are worth it, some people swear by them for toning.

There are three levels of strenght. Positiv, static, negative. For example: You can lower more weight slowly than you can hold it static, and you can hold more weight static, than you can push/pull. So holding weights is only one of the three parts used, when working out. I would always reccommend haveing a normal positive phase, a short but existent static phase, and a slow negative phase, for an optimal strength workout.
Further more, when holding weight up for longer times than you normally do, you can change fast twitching muscel tissue to slow twitching. But I guess that's more information, than you are looking forward.

But I think a short static phase, when working out with weights, is always good. You work out much more intensely, compared to the way most of the people train.

Thanks for that advice, I do try to do my weights more slowly, as my PT used to show me. Have lowered my weight n upped repetition and holding my core tight as I can when working out.
