Which weathering process involves the constant freezing and thawing of water?

True

Explanation:

If we eat an hour before the exercise then our body gets enough energy to carry out the physical activities. Extending more than two hours of a meal before the exercise is not advisable.

Consuming carbohydrate and protein rich food after the exercise is a must as it stimulates the synthesis of muscle protein. Working out in an empty stomach or after a light meal is not suggested as the body burns more fat during the exercise even when enough food is not consumed.
