Mikey,
When you taste your own sweat what does it taste of?....Salts right?...or put another way..minerals....
Do you take a mineral suppliment mate?... You definitely should if you train, jog or exercise regularly..
The other thing that is very helpful is L-Glutamine. Take one or two spoonfuls in water an hour before training. It achieves two things:
1. When you exercise your small intestine pulls glutamine from your muscles. This is one of the reasons you ache afterwards. So if the glutamine is already in your intestine it doesn't sap it from the muscles concerned.
2. Glutamine helps the muscles repair more quickly, so you have negligable aching the next day....
Lastly, remember, moderation is the key, in training or otherwise...stress your engine too much and it can blow up permanent...
