Electrolyte supplementation
Added sodium, potassium and magnesium, especially when fasting or sweating
Powdered or tablet sodium, potassium and magnesium in water, used around training, in the sauna, in the heat, or while fasting. The case rests on heavy sweating and on low-carbohydrate eating, both of which increase sodium losses. It thins out for someone eating a normal diet and sitting at a desk.

Water with a pinch of sea salt in it, straight after training. That is his first recovery step, on the grounds that a slightly dehydrated body will not start the protein synthesis work. He is obsessive about it, he says, and thinks he under-hydrates rather than over-hydrates.
