You can eat apples after exercise, but don't eat them immediately. It is recommended to breathe evenly after stopping exercise, otherwise it will be easy to suffocate and is not conducive to digestion. Apples contain polyphenols, which can increase muscle strength, and oranges contain vitamin C, which can increase the production of nitrous oxide. I recommend you to eat these two fruits alternately, or eat apples during weight-bearing training and oranges during low-intensity training. Note: Vitamin C is lost with the loss of body water during exercise, so it is a good choice to supplement fruit in time. Apples contain potassium ions. Supplementing potassium ions after exercise helps to restore physical strength and maintain blood acid-base balance, so it is good. Of course, we should replenish enough water, eat more carbohydrates and protein's rich food to consolidate the exercise effect.
