The first nutritional priority after exercise is to replace any fluid lost during exercise. In general the best way to determine how much to drink (either water of a sports drink) is to:

• Weigh yourself before and after exercise and replace fluid losses.
• Drink 20-24 fl oz water for every 1 lb lost.

Some bodybuilders take in four or five times as much as the RDA—and, according to this research, totally unnecessarily.
