One tool in understanding your given physical status before and after exercise is the simple act of recording your weight.

I've seem these Internet threads go back and forth about some mineral or sugar supplement but ignore the most basic principle of all. To exercise and feel well afterwards - you need to keep yourself hydrated. If you are concerned about your well being - then weighing yourself is the starting point of any inquiry.

Assuming you have some mineral imbalance without even understanding what your "healthy" body weight should be seems silly to me.

However, my comments are routinely ignored and disparaged. Perhaps using a scale is too inconvenient for most readers.
