To optimise your muscles for speed, you need low load, repetitive, 
sustained and fast exercises.

Doing the classic biscep building routine WITHOUT weight at about 50 to 
60 flexions/extentions per minutes would be a nice example.

Then, whatever you do that use your muscles, will initialy burn fat. 
Then, in the long term, you'll start to gain weight as you build up 
muscle mass faster that you burn fat. And remember: muscle dencity is 
larger than 1 (sink in water) while fat dencity is less than 1 (float in 
water). That's why I don't float, I don't have enough body fat and my 
muscles and bones have a somewhat above average dencity. It makes it 
prety hard to learn to swim...
