Ive been doing the fitness 4x4 hour of power for about 2 months now, and I have to say it has been one of the best fitness tools ive come across.

Ive been fit for years, loads of cycling and swimming, but at about christmas I decided I wanted to get strong in my upper body. I did the Mr Mansized thing, started lifting heavy weights, got a bit stronger.

Then I started this hour of power in May, and well the different in me now is really apparant. The whole idea of the session is to lift light weights at high tempo. Therefore exercising both your muscles and cardio system. Whilst it might not be effective for pure weight lifting beefcakes, for average blokes, it certainly has worked for me.

Strength it does give you, it is run by Rajko Radovic (was on BBCs last man standing) and the hour of power was devised by his father 30 years ago. Rajko is the world record holder for dumbell curls, and his father has never been beaten in a dumbell curl event...and the basis of their training is the hour of power. Seriously it has really worked for me...has anyone else tried it?
