Training for increasing swing speed

[ronaldkuntoro]

Will training with a heavy iron increase your swing speed ?

This heavy iron is an old 9 iron with a heavy steel shaft.
Currently I'm using 75 g graphite shaft on all my irons.

I think a heavy club is good for stretching and warming up and perhaps some strengthening. But IMO, swing speed is 80% technique (includes flexibility), 10% strength, and 10% size (i.e. a 6'4" golfer vs. a 5'9" golfer), so it's not something I would look to dramatically increase my distance. I suppose if it could help with your technique (e.g. using larger muscles) then it could have some tangible benefits.

personally i think it messes up your timing.
