Exercise at night

Principle: Exercise within 1 hour after meals is easy to feel tired, because muscle activity needs oxygen-enriched blood, and blood flows to the digestive tract at this time. It is better to do exercise three hours after supper. You can replenish water moderately after exercise, but don't supplement food in large quantities, so as not to affect digestion and sleep.

Recommendation: a starchy staple food (such as rice, macaroni and potatoes), or other cereals; Two kinds of fruits.
