DEHYDRATION - NOT JUST LACK OF WATER.
When you Spin®, you sweat. But it’s not just water you lose. Vital salts are lost, too. The good news is that these salts, or ‘electrolytes’ are present in everyday foods.
Calcium - which isn’t just good for bones and teeth. It also helps regulate the permeability of cell walls, which has a knock-on effect on muscles, nerves, glands and blood vessels. Drink milk - the best source of calcium.
Potassium - deficiency leads to muscle spasms, weakness and cramps. Up to 90% of potassium is found in the fluids within cells. Potatoes, oddly enough are the answer. They contain twice as much as bananas, which is what people normally reach for.
Magnesium - the slow-burn endurance electrolyte. Regulates your blood sugar levels. Pulses like lentils are a great source.
Sodium - when levels drop, your body hangs on to water and sodium retention. Which gives you puffy hands and feet. You need to make sure you get plenty of sodium for physical activity but should keep it low in everyday life.
Chloride - this regulates your stomach acid levels and is present in table salt, so not likely to be lacking. Avocado and kelp are rich in chloride.
