With the legs held perfectly straight lift the feet six inches off the floor and hold. I's difficult at first so hold for 5. Then bring slowly back to the floor.

It can be made more difficult with ankle weights, simply increasing the time, a medicine ball or varying leg movements.

I find it great for the lower abs and the beltline where punches occasionally stray.

I do these with leg weights on and you are right they are brilliant for the lower abs, you just have to make sure you dont bend your legs while doing them and also be carefull not to hurt your back.
