First of all, I tell you that you can exercise completely. But it is best to eat 1-2 pieces of oatmeal bread and a banana before exercise. Mainly to supplement energy and carbohydrates.

Walking every day is very tiring, mainly consuming energy, that is, glucose. If your body is short of sugar, you will feel very tired.

Exercising muscles consumes energy, but proper supplementation is enough to resist the consumption of fitness. It is more important to stretch your muscles and promote muscle growth with the help of the public. Consume more creatine and phosphocreatine in muscles, so you can exercise completely.

But don't eat immediately after exercise. After 20-30 minutes, add protein and eat.
