Thank you for your response. It seems that — as mentioned above — I created this account while I was at training. Then — as things can happen at training — I lost sight of things and totally forgot I had an account here.
Anyways, better late than never, and so thank you for your response to my question about muscle cramps. During training I quickly found out about using salt, and that was helpful.
Over the years I have come across a few other things which future readers of this thread may find useful: The combination of bananas and coconut water goes a long way!
