If you want to train harder and recover faster, then it is very important to start each training session well hydrated, to carry on rehydrating throughout the training, as well as, to restore hydration levels immediately after your workout; so that water and electrolytes lost in sweat are fully replaced.
According to the British Dietetic Association (BDA), the general rules for your choice of drink are:
- Low to moderate intensity exercise (1 hour or less) ➺ drink water
- Moderate to hard sessions (more than 1 hour) ➺ drink an isotonic drink (see how to make your own home-made drink here).
